Protests have kicked off for the second day of President Donald Trump’s U.K. visit as tens of thousands of demonstrators assemble in central London and cities around the country.

London protesters fly big Trump balloon

Protesters in London flew a giant balloon depicting US President Donald Trump as an angry baby. Trump told the newspaper 'The Sun' that he felt unwelcome in London because of protests.

Protesters are out in force UK-wide, with people already taking to the streets of London, Cambridge, Bristol and Newcastle.

More than 200 armed with pots and pans, drums, whistles and vuvuzelas tried to make a "wall of sound" outside Winfield House, where Trump and the First Lady are spending the night after the banquet at Blenheim Palace.

Trump depicted as the devil in Bristol

Crowds chanting “say it loud, say it clear, Donald Trump’s not welcome here” played harrowing audio of children crying who have been separated from their parents on the US border.

Bristol city centre was brought to a standstill as protesters marched bearing signs and chanting "Hey, ho, Donald Trump has got to go".

Security for his visit has been ramped up as part of a £30million operation.
