US President Donald Trump and First Lady Melania Trump have arrived in the UK for a three-day state visit.
Air Force One landed at Stansted Airport at around 09:00 BST (04:00 ET).
Mr Trump will meet members of the Royal Family, and is expected to discuss climate change and Chinese technology firm Huawei during talks with outgoing Prime Minister Theresa May.
Minutes before touching down, Mr Trump criticised Mayor of London Sadiq Khan, with whom he has clashed in the past.
He tweeted that Mr Khan – who had earlier said the UK should “not roll out the red carpet” for Mr Trump – was a “stone cold loser”, but the president added he was looking forward to his visit.
Protests are planned in several UK cities during the visit, including London, Manchester, Belfast, and Birmingham.
Mr Trump was greeted by US Ambassador to the UK Woody Johnson and Foreign Secretary Jeremy Hunt.
Tory leadership candidate Mr Hunt, who has spoken about the importance of the UK’s relationship with the US, said Mr Trump mentioned to him “some of his very strong views about the Mayor of London” which he had also tweeted.
