LONDON (AP) — Leading Brexit supporters are talking tough, and opponents are taking to the streets, on the second anniversary of Britain's vote to leave the European Union.

Saturday marks two years since a June 23, 2016 referendum resulted in a decision to quit the 28-nation EU. Britain is due to leave the bloc on March 29, 2019, but its government remains divided about what kind of economic relationship it wants with the EU after Brexit.

Pro-Brexit Foreign Secretary Boris Johnson urged Prime Minister Theresa May to deliver a "full British Brexit," rather than one he compared to toilet paper — "soft, yielding and seemingly infinitely long."

Meanwhile, thousands of opponents of Brexit are due to rally outside Parliament, calling for a referendum on any final divorce deal between Britain and the EU.
