London joined cities across the globe in hosting anti-Donald Trump protests ahead of the US president-elect’s inauguration ceremony in Washington, DC.

Protesters took action in more than 150 locations across Britain.

A 25-meter-long banner reading “Bridges Not Walls” was dropped from London’s iconic Tower Bridge in the early morning.

Many other bridges over London’s River Thames were included in the protest, among them Westminster Bridge next to the Houses of Parliament, where campaigners held a banner reading “migrants welcome here.”

So proud of @TheGreenParty for being the only UK political party to throw our full public support behind #bridgesnotwallspic.twitter.com/KnMtj9Rs8m — Rachel Collinson (@rachel_shares) January 20, 2017

“On Trump’s inauguration day we’re taking action to show our support for groups under attack – here in the UK, across Europe and in the USA – and to reject the rise of a dangerous and divisive far-right politics,” said Bridges Not Walls campaign spokeswoman Nona Hurkmans.

“We won’t let the politics of hate peddled by the likes of Donald Trump take hold. What happens next is up to us and by standing together we can show that the rhetoric of fear and hate have no place in our society.”

Freezing temperatures and mist did not stop protesters, who were supported by the Green Party, the Liberal Democrats’ LGBT group and environmentalist group People & Planet.

“We are part of a wider action going right across the UK about bridges not walls, that’s on the day of Trump’s inauguration to say we can be so much better than this,” Green Party co-leader Jonathan Bartley said at the Tower Bridge stunt.

“We need to reach out, we need to recognize that we are citizens of the world. And as the Green Party, we are particularly making a point about refugees. We want better resettlement of refugees in the UK and more protection in particular for refugee children.”

The campaign was reportedly the brainchild of an ice cream seller and homeless shelter worker in Hastings, Will Stevens, who was shocked by the result of the US election.

Republican candidate Trump won the White House despite losing the popular vote with 46 percent of ballots against Democratic rival Hillary Clinton’s 48 percent.

Similar actions took place in other world capitals, including Dublin, Rome, Berlin, Toronto, Sidney and even Addis Ababa in Ethiopia.
