LONDON—Tens of thousands of European Union supporters sang, danced and marched their way down the streets of London on Saturday to protest the United Kingdom’s vote to leave the EU.

Many participants in the celebrity-peppered 2-mile (3-kilometer) “March for Europe” from Hyde Park to Parliament said they expect the government and British lawmakers to balk on leaving the 28-nation bloc despite 52 percent voter support for the move in the June 23 referendum.
