The Prince of Wales has arrived in Estonia for the start of a two-day visit to show support for UK troops guarding Nato’s border with Russia.

Prince William began his trip on Thursday by sitting down for talks in the capital Talinn with Estonia’s president Alar Karis, who has been prominent among those giving military equipment and political support to Ukraine.

William is travelling to Estonia predominantly in his role as Colonel-in-Chief of the Mercian Regiment – which is taking over Nato defence duties in the country from the Royal Dragoon Guards.

On the second day of the visit, the royal will travel to attend a handover ceremony at the Tapa Army Base, which houses the UK’s largest permanent overseas deployment. There are around 800 British service personnel in total in Estonia.

William will meet both soldiers from his regiment and Estonian troops based at Tapa, where forces are stationed ready to defend Nato’s eastern flank.

British forces are deployed to Estonia and Poland under Operation Cabrit, the UK’s contribution to Nato’s Forward Land Forces in the two countries.

Estonia’s defence minster Hanno Pevkur told ITV News: “The reality is we cannot change our neighbour – our neighbour is very hostile towards its neighbours, this is our response to how Russia is acting at the moment.”

William’s visit comes as Europe’s major nations including the UK prepare to step up spending on their armed forces in response to the changing world order ushered in by US President Donald Trump.

Russia is seen as a growing threat in the region following its three-year long invasion of Ukraine, and the Baltic states – Estonia, Lithuania and Latvia – which border Russian President Vladimir Putin’s nation appear increasingly concerned.
