Donald Trump appeared to stumble over his words while speaking at a joint press conference with Theresa May in London.

The US president paid tribute to British and American forces who fought on D-Day, ahead of the 75th anniversary of the event, while speaking to journalists on Tuesday.

“On 6 June 1944 tens of thousands of young warriors left these shores by the sea and air ... to begin the invasion of Normandy and liber...ation of Europe,” he said, stumbling over the word “liberation”.

A few moments later he managed to say the word without struggling.

“It was a liberation like few people had seen before,” he said.
