The Queen has paid tribute to the “heroism, courage and sacrifice” of those who died in the D-Day landings.
She was joined by 16 world leaders, including US President Donald Trump, in Portsmouth to commemorate the 75th anniversary of history’s largest combined land, air and naval operation.
Mr Trump, who was on the last day of his UK state visit, said D-Day “may have been the greatest battle ever”.
Veterans of the landings in Normandy to liberate western Europe also attended.
She thanked them “with humility and pleasure, on behalf of the entire country, indeed the whole free world”.
The countries represented at the event have agreed to make a joint statement pledging to ensure the “unimaginable horror” of the war is not repeated.
Called “the D-Day proclamation”, the 16 signatories – including the UK and the US – will commit to working together to “resolve international tensions peacefully”.
On Thursday, further memorial services are 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.
Leaders from every country that fought alongside the UK on D-Day joined the Queen and the Prince of Wales for the commemorations on Southsea Common.
They included 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.
