World leaders, including Donald Trump, joined Queen Elizabeth in Portsmouth, England on Wednesday to commemorate the 75th anniversary of the D-Day landings.
Theresa May hosted 15 world leaders to honor the largest combined land, air and naval operation in history.
Figures from every country that fought alongside the UK were in attendance.
Coming at the end of a three-day state visit to the UK, Trump said he was looking forward to marking what “may have been the greatest battle ever”.
The countries represented at the event have agreed to make a joint statement pledging to ensure the “unimaginable horror” of World War Two is not repeated.
Called “the D-Day proclamation”, the 16 signatories – including the UK and the US – all committed to working together to “resolve international tensions peacefully”.
The UK prime minister used the occasion to call for continued Western unity in tackling what she will call “new and evolving security threats”.
On Thursday, memorial services were planned to mark the 75 years since the D-Day landings on 6 June 1944 – the start of the campaign to liberate Nazi-occupied north-west Europe.
The Queen and the Prince of Wales attended the commemorations on Southsea Common, along with representatives from the countries that fought alongside the UK in the Battle of Normandy including French President Emmanuel Macron, US President Donald Trump and Canadian Prime Minister Justin Trudeau.
Also attending were German Chancellor Angela Merkel, as well as leaders from Australia, Belgium, Czech Republic, Denmark, Greece, Luxembourg, the Netherlands, Norway, New Zealand, Poland and Slovakia.
All the leaders signed the proclamation on the bottom…except for Trump who signed the top of the document, and his signature was larger than everyone else’s.
