German Chancellor Friedrich Merz has cautioned world leaders that the rules-based global order is no longer in effect, speaking at a prominent security summit.

In his opening address at the Munich Security Conference, Merz emphasized that the freedom of Europeans is not guaranteed in the current era of major power politics, and that they must be prepared to make sacrifices.

Merz also acknowledged a significant rift between Europe and the United States, seemingly alluding to US President Donald Trump's controversial remarks about annexing Greenland and implementing tariffs on European nations.

US Secretary of State Marco Rubio, who attended Merz's speech and is scheduled to deliver his own address on Saturday, previously discussed the emergence of a new geopolitical era.

Approximately 50 global leaders are expected to attend this year's conference, where key topics such as European defense and the future of transatlantic relations will be discussed.

The conference takes place amidst uncertainty surrounding US commitments to the Nato military alliance, as well as concerns over Trump's aspirations to acquire Greenland, which have eroded trust between the US and its European allies.

The ongoing Russia-Ukraine conflict, tensions between the West and China, and potential developments in the Iran-US nuclear deal are also on the agenda at the annual gathering.

Merz warned the conference that the rules-based order has effectively ceased to exist, stating, "I fear we must be more direct: this order, despite its imperfections, no longer exists in its current form."

He also noted that a significant divide has emerged between Europe and the United States, referencing remarks made by Vice-President JD Vance at the Munich conference the previous year.

Merz emphasized that Europeans do not share the same cultural values as the US, particularly with regards to the MAGA movement, and that they prioritize human dignity, free trade, and the constitution over protectionism and tariffs.

Vance's speech last year sparked a year of unprecedented tension between the US and Europe, particularly with regards to policies on free speech and immigration.

Despite these challenges, Merz expressed his desire to revitalize and restore trust between the US and Europe, rather than abandoning their long-standing partnership.

The German leader also revealed that confidential discussions are underway with French President Macron to establish a joint European nuclear deterrent, although no further details were provided.

Currently, France and the UK are the only nuclear-armed nations in Europe, while other European countries, including Germany, have traditionally relied on the US nuclear umbrella within the Nato alliance for deterrence.

Prior to the Munich conference, Rubio cautioned that the world is undergoing rapid changes, and that this new era in geopolitics will require a re-examination of roles and relationships.

Rubio stated, "We are living in a new era of geopolitics, and it will necessitate a re-evaluation of our positions and the role we will play in this changing world."

Tensions have escalated in recent months due to Trump's repeated assertions that Greenland is crucial to US national security, claiming without evidence that the territory is frequented by Russian and Chinese ships.

On Friday, Danish Prime Minister Mette Frederiksen announced plans to meet with Rubio to discuss the US threats to Denmark's semi-autonomous territory of Greenland, which is a Nato ally.

DP World's global ports operator has undergone a change in leadership, with the previous head stepping down amidst scrutiny surrounding their association with convicted sex offender Jeffrey Epstein.

Sultan Ahmed bin Sulayem's departure as chairman and chief executive follows the release of newly uncovered files, which indicate he exchanged numerous emails with Epstein over the course of a decade.

The mention of an individual in these files does not imply any wrongdoing, and the BBC has reached out to Sulayem for a statement regarding the matter.

On Friday, DP World announced the appointments of Essa Kazim as chairman and Yuvraj Narayan as chief executive, without making any reference to Sulayem, whose photograph appears to have been removed from the company's website.

DP World, a Dubai-owned logistics company with a significant presence in global trade infrastructure, operating port terminals across six continents, has faced increasing pressure from its business partners in recent days.

Earlier in the week, the UK development finance agency and La Caisse, Canada's second-largest pension fund, announced that they would be suspending new investments in the firm.

Additionally, the Prince of Wales' Earthshot project, which received funding from DP World, was reported to the UK Charity Commission following Sulayem's appearance in the recently released files.

The documents suggest a close and extensive relationship between Sulayem, a prominent Gulf business figure, and Epstein, spanning multiple areas of interaction.

US lawmakers Ro Khanna and Thomas Massie have accused Sulayem of being one of several influential individuals associated with Epstein, citing him as one of "six powerful men" linked to the disgraced financier.

The lawmakers, who co-sponsored the legislation that led to the release of the Epstein files last year, claim that certain information was improperly redacted from the documents.

On 9 February, Thomas Massie highlighted a redacted document that appeared to contain an email from Epstein in 2009, referencing a "torture video"; the recipient responded that they would be traveling between China and the US, although the context of the exchange is unclear.

US officials have confirmed that Sulayem was the recipient of the email in question, which was sent by Epstein.

Ireland captain Caelan Doris is urging his team to deliver a strong performance against Italy, following their disappointing loss to France last week.

Historically, Ireland have dominated Italy in their home Six Nations matches, winning their last five encounters by at least 30 points, including a 2024 match where they held Italy scoreless, but a similar outcome is not expected this time around.

Italy's confidence is high after their 18-15 victory over Scotland in Rome, where they excelled in the set-piece and defended well in the closing stages.

Gonzalo Quesada's team put in an impressive display despite the challenging weather conditions, and their win has given them momentum ahead of their trip to Dublin.

In contrast, Ireland's camp has been introspective after their 16-year-low Six Nations loss to France, with head coach Andy Farrell expressing his disappointment and the need for improvement.

Farrell was critical of his team's performance, particularly in the first half, and has made several changes to the lineup for the Italy match, including the exclusion of Josh van der Flier, Jacob Stockdale, Tommy O'Brien, and Cian Prendergast.

The Irish coach has also spoken about the need for his team to "simplify things" and understand their identity, following a clear-the-air meeting with the squad.

Farrell has emphasized the importance of players not overthinking their roles and instead focusing on their strengths, as they prepare to face Italy.

The Irish coach's message to his players is to trust their instincts and not overcomplicate their game plan against Italy.

Ireland's review of their loss to France was a candid and honest assessment, with players and coaches alike acknowledging the need for improvement.

Ireland has made six changes to their team for the Italy match, with newcomers Cormac Izuchukwu and Rob Baloucoune, as well as uncapped lock Edwin Edogbo, set to feature.

Captain Caelan Doris believes that the new players must take ownership of their roles and contribute to the team's overall performance.

Doris expressed his enthusiasm for the team's lineup, despite the changes, and emphasized the importance of cohesion and trust among the players.

The Irish captain's message to the new players is to have faith in their abilities and enjoy the experience, while also focusing on the team's core strengths.

Doris stressed that every player must be fully committed and take responsibility for their actions on the field, in order to achieve a positive outcome.

He added that creating a sense of unity and purpose through their actions can have a profound impact on the team's performance.

Doris reiterated that every player must be fully invested and take ownership of their role, in order to achieve success against Italy.

Edwin Edogbo, the towering Munster lock, is set to make his Test debut for Ireland on Saturday.

Ireland's loss to France was marked by a lack of intent, and head coach Andy Farrell has responded by making changes to the team, including the inclusion of wingers James Lowe and Rob Baloucoune.

The hope is that these changes will help Ireland to rediscover their sense of purpose and direction against Italy.

Lowe, a experienced player, was dropped for the France match, but returns to the lineup, while Baloucoune makes his first appearance for Ireland since November 2022.

The inclusion of Cormac Izuchukwu in the back row is expected to add dynamism and ball-carrying ability to Ireland's attack.

There is also excitement about the potential of Edwin Edogbo, who has impressed for Munster despite struggling with injuries earlier in his career.

Caelan Doris will switch back to open-side flanker, a position he has played before against Italy, and where he has scored tries in the past.

Regardless of his position, Doris is focused on helping Ireland to move past their loss to France and deliver a strong performance against Italy.

The Irish captain reflected on the team's discussions throughout the week, which have centered on accountability, simplicity, and a renewed focus on their core values.

Doris emphasized the importance of the team holding each other accountable and taking ownership of their actions, in order to drive improvement.

The Irish captain acknowledged that the loss to France has served as a reference point, but expressed confidence that the team can learn from the experience and move forward.

Doris believes that Ireland has the potential to improve, but must focus on executing their game plan effectively and trusting their strengths.

The match between Ireland and Italy is scheduled to take place on Saturday, 14 February, at 14:10 GMT.

The Aviva Stadium in Dublin will host the encounter.

Fans can listen to live commentary of the match on BBC Sounds, BBC Radio 5 Sports Extra 2, BBC Radio Ulster, and the BBC Sport website and app, as well as follow live text commentary.

Italy has a chance to cause a major upset in the Six Nations, and will be looking to build on their win over Scotland last week.

The Italians pushed Ireland close last year, losing 22-17, and will be hoping to go one better this time around.

Despite the absence of Juan Ignacio Brex, Italy has a number of threats, including Tommaso Menoncello, one of the most exciting young talents in European rugby.

The Italian forwards have shown their ability to compete with top teams, having dominated Scotland and caused problems for South Africa's pack in November.

Caelan Doris acknowledged that Italy is no longer just a passionate team, but a side with a well-rounded attack and strong defense.

The Irish captain noted that Italy's attack is now a significant threat, and that their ability to play with width and depth makes them a challenging opponent.

Doris also highlighted the improvement in Italy's scrum, as well as the quality of their back three and the physicality of their forwards.

The Ireland team to face Italy is: Osborne; Baloucoune, Ringrose, McCloskey, Lowe; S Prendergast, Casey; Loughman, Sheehan, Clarkson, McCarthy, Ryan, Izuchukwu, Doris (capt), Conan.

Ireland's substitutes for the match include Kelleher, O'Toole, Furlong, Edogbo, Beirne, Timoney, Gibson-Park, and Crowley.

The Italian team features Pani, Lynagh, Marin, Menoncello, and Ioane in the backline, with P Garbisi and Fusco in the half-back positions, and a forward pack consisting of Fischetti, Nicotera, Ferrari, N Cannone, Zambonin, Lamaro as captain, Zuliani, and L Cannone.

Italy's replacement players are Di Bartolomeo, Spagnolo, Hasa, Ruzza, Favretto, Odiase, A Garbisi, and Odogwu.

On Saturday, Hollie Davidson of Scotland will make history by becoming the first female referee to officiate a men's Six Nations match, with the fixture being Ireland's home game against Italy.
