Thousands of European Union supporters are singing, dancing and marching through the streets of London to protest the United Kingdom's vote to leave the EU.

Saturday's 2-mile (3-kilometer) "March for Europe" from Hyde Park to Parliament was organized on social media. Many of the marchers say they expect lawmakers to block any moves to leave the 28-nation bloc, a move backed by 52 percent of voters in the June 23 referendum.

One organizer, comedian Mark Thomas, says British lawmakers should not legislate for an exit based on a result driven by anti-EU campaigners' exaggerations and distortions on immigration and EU spending.

Thomas said: "We would accept the result of the referendum if it was fought on a level playing field. But it was full of misinformation."
