Leading Brexit campaigner Nigel Farage was booed and heckled in a raucous special session of the European Parliament on Tuesday as he accused the EU of imposing a superstate on its citizens and predicted other countries would follow Britain in leaving the bloc.

Facing Farage, who sat with a British flag on the table in front of him, European Commission President Jean-Claude Juncker asked, "Why are you here?"

When Farage interrupted Juncker's speech to applaud the results of last week's British vote to leave the EU, the commission chief shot back, "That is the last time you are applauding here."
