Nigel Farage unveiled hundreds of Brexit Party candidates for Britain's general election on Monday, and warned the governing Conservatives that the UK will never leave the European Union without his party's backing.
All seats in the 650-seat House of Commons are up for grabs in the Dec. 12 election. Farage says his party will run in almost every constituency unless Prime Minister Boris Johnson scraps his EU divorce deal.
Johnson hopes to win a Conservative majority so that he can break the country's Brexit deadlock and get his EU divorce deal through Parliament.
Farage, who has run for Parliament seven times without success, says he won't be a candidate himself.
Farage's party, which was founded earlier this year, rejects Johnson's Brexit deal, preferring to leave the bloc with no agreement on future relations in what it calls a "clean-break" Brexit.
The party says leaving with a deal, as Johnson wants, would mean continuing to follow some EU rules and holding years of negotiations on future relations.
Farage told a crowd of supporters at a rally in London that Johnson's deal "is not Brexit. It is a sell-out." Farage called the Conservatives are arrogant for not joining him in a "leave alliance."
"There will be no Brexit without the Brexit Party," he said. "Of that I am certain."
US President Donald Trump, a friend of Farage, also urged the two politicians to form an electoral pact, saying last week that Farage and Johnson together would be "an unstoppable force."
