Donald Trump and Melania Arrive Hand-in-Hand in London for Their 3-Day-Visit

US President Donald Trump and First Lady Melania Trump arrived in the UK earlier today for a three-day state visit.

The POTUS and FLOTUS arrived in the UK on Air Force One. They landed at Stansted Airport at around 09:00 BST (04:00 ET).

The trip is an official three-day state visit to meet members of the Royal Family. The President is also expected to discuss climate change and Chinese technology firm Huawei during talks with outgoing Prime Minister Theresa May.

Mayor of London Sadiq Khan had stated that in his opinion the UK should "not roll out the red carpet" for Trump. Just before landing, however, President Trump caused a social media frenzy with his response to Khan's comment.

Trump lashed out at the mayor on Twitter. In a scathing reply, Trump criticized Khan, whom he has clashed with on other occasions as well.

Trump was greeted by US Ambassador to the UK Woody Johnson and Foreign Secretary Jeremy Hunt during his arrival in the UK. Hunt, a Tory leadership candidate, has spoken about the importance of the UK's relationship with the US regularly.

The Trumps will attend a state banquet at Buckingham Palace hosted by the Queen.

He revealed that Trump spoke to him about "some of his very strong views about the Mayor of London." A spokesman for Khan said "childish insults" should be beneath the US president.

"Sadiq is representing the progressive values of London and our country, warning that Donald Trump is the most egregious example of a growing far-right threat around the globe," said the representative.

With regards to the schedule of his visit, Trump will begin talks with Theresa May on Tuesday. Although Trump has spoken of his admiration for May the two may butt heads on some points during their talks.

May will raise the issue of climate change. The topic comes just after a government spokesman revealed that the UK was "disappointed by the US decision to withdraw from the Paris Agreement in 2017".

The two leaders are also expected to discuss Huawei. The Chinese firm was blacklisted in the US for security reasons however the UK may allow it to supply "non-core" components for its 5G network.

On Monday, the president will be given a tour of Westminster Abbey and meet Prince Charles and the Duchess of Cornwall for tea at Clarence House. In the evening, the Trumps will attend a state banquet at Buckingham Palace hosted by the Queen.

The Duke and Duchess of Cambridge will be in attendance. However, the Duchess of Sussex will not attend as she is still on maternity leave.
