Farage issues warning over 'Brexit betrayal'

LONDON - If Prime Minister Theresa May allows Brexit to be watered down or halted by supporters of European Union membership, Britain will be thrust into its gravest constitutional crisis since World War II, Brexit campaigner Nigel Farage said.

Farage, who as UKIP leader convinced Prime Minister Theresa May's predecessor, David Cameron, to call the Brexit referendum and then helped lead the campaign to leave the EU, said Brexit was now in danger of being scuttled by the establishment.

The 53--year--old former commodities trader cast May, who voted to stay in the EU, as "Theresa the appeaser" for giving in to Brussels on almost every element of Brexit negotiations and said Britain was being humiliated by the EU.
