Donald Trump's state visit to the UK in pictures

President Trump has embarked on the first day of his three-day UK state visit, joined by his wife, First Lady Melania Trump.

Mr Trump was welcomed with a 41-gun salute as he met the Queen at Buckingham Palace.

Here are pictures from the visit, starting on Monday.

After landing at Stansted Airport, President Trump and First Lady Melania Trump appeared on the steps of Air Force One, moments after Mr Trump tweeted comments about London Mayor Sadiq Khan, calling him a "stone cold loser" and accusing him of being "nasty"

The tweets followed recent criticism of Mr Trump from Mr Khan, who said the UK should not be "rolling out the red carpet" for the US president during the trip
