A banner reading “Build Bridges Not Walls” was draped across London’s tower bridge today as part of a series of events across the world aimed at expressing displeasure at the inauguration of Donald Trump as U.S. President.

Protesters on the iconic bridge held up pink letters reading “Act Now!” soon after sunrise while others unfurled the banner over the railings.

The protest in London was organised by the campaign group also called “Bridges Not Walls”, in reference to trump’s pledge to build a wall on the Mexican border.

The republican’s supporters admire his experience in business, including as a real estate developer and reality television star, and view him as an outsider who will take a fresh approach to politics.

Trump has repeatedly pledged to “Make America Great Again” and said on twitter that he would fight very hard to make his Presidency a great journey for the American people.
