Trump UK Visit: Hundreds of Thousands Set to Protest on 2nd Day

The main demonstration against the president's trip is scheduled for Tuesday, with as many as 250,000 activists expected to march from Trafalgar Square to Downing Street, Evening Standard reported.

Labor leader Jeremy Corbyn is gearing up to lead the demonstration, which has been planned to coincide with the US President's talks with the Prime Minister.

Corbyn said he would address demonstrators on Tuesday "in solidarity with those (Trump) attacked in America, around the world and in our own country".

It comes after a huge security operation was launched yesterday in the capital, with Scotland Yard placing streets surrounding Buckingham Palace and Downing Street in “lockdown” with around 10,000 police officers deployed in a £25 million operation.

Thousands of activists are expected in central London as the US president meets May, although the police operation will mean they cannot demonstrate outside the entrance to Downing Street.

Corbyn, who refused an invitation to Monday evening's state banquet, is due to be joined by other political parties including members of the Liberal Democrats and the Green Party.

Across the UK, protests in Birmingham, Stoke, Sheffield, Glasgow, Edinburgh, Chester, Leicester, Oxford and Exeter are also planned.

The US leader said on Monday he had only seen "tremendous crowds of well-wishers" and that he expected "fake news" would be "working hard" to find protesters.

It comes after a day of pomp and ceremony as Trump was welcomed by the Queen and lunched at Buckingham Palace with senior royals.

Amid Monday’s formalities, which included a visit to Westminster Abbey and tea at Clarence House, and a state banquet at Buckingham Palace, Trump tweeted that the trip was "going really well" and the royal family had been "fantastic".

He then used the occasion to praise the Queen's "spirit of dignity, duty and patriotism that beats proudly in every British heart".

Trump told the Buckingham Palace banquet guests, who included senior royals, captains of industry and other leading figures from national life: "As we honor our shared victory and heritage, we affirm the common values that will unite us long into future.

"Freedom, sovereignty, self-determination, the rule of law and reference for the rights given to us by Almighty God. From the Second World War to today, Her Majesty has stood as a constant symbol of these priceless traditions."

In her address, the Queen celebrated the special relationship between the UK and the US, and while Brexit was not mentioned she highlighted how the two countries faced "new challenges of the 21st century".

However, the president's visit started with a series of controversial Twitter messages, with tirades against the London mayor, "fake news" and China.

Moments before he and the First Lady touched down at Stansted Airport, Trump had called London Mayor Sadiq Khan a "stone cold loser", but misspelled his surname in one of the posts.

He had also been forced to deny calling the Duchess of Sussex "nasty" shortly before the visit when he was confronted with comments she made before the 2016 US presidential election saying she would leave the country if he won.

On Tuesday, Trump and Prime Minister Theresa May will co-host a business breakfast meeting with senior UK and US business leaders. The event at St James's Palace will also be attended by the Duke of York.

The US leader will hold talks with May at 10 Downing Street, after which they will give a press conference.

In the evening, Trump and the First Lady will host a dinner at Winfield House - the official residence of Woody Johnson, the US ambassador to the UK - in Regent's Park, which will be attended by Charles and Camilla, who will represent the Queen.
