Tens of thousands of people took to the streets last night to protest against US President Donald Trump's ban on visitors from seven Middle Eastern countries.
Controversy has brewed in the UK over whether Trump should come on a state visit. He has been invited, but more than one million people have signed a petition saying the invite should be revoked.
Last night, Londoners protested against Trump outside 10 Downing Street, but campaigners also filled the city centres of Leeds, Manchester, Glasgow, York, Newcastle, Oxford and Cambridge.
Here are the best signs and tweets from the demonstrations:
Trump, of course, was pummelled with abuse
But the Cambridge protest seemed more civilised
Scotland was true to form as well
Creatives were out in force
Some people were not cool with how TV and reality have started to blur
But others wished our favourite film characters would take the helm
History was, of course, a big theme
The left protest about Trump, but they're strangely silent about King Raedwald's invasion of Northumbria in AD 616— Andy Riley (@AndyRileyish) January 31, 2017
But one important public figure was left out of the action
I've been locked inside during the Trump protest - not because of my safety; they're worried I'd join in. #StandUpToTrump— Larry the Cat (@Number10cat) January 30, 2017
