Brexit's Long Term Economic Impact

MP Nigel Farage says British Prime Minister Boris Johnson should ditch his Brexit deal and "build a leave alliance." At the launch of the Brexit Party's election campaign, the leader said bringing the parties together was "the only way" forward.

The Conservatives have consistently ruled out a formal pact with the party. This follows President Donald Trump saying that Farage and Johnson should team up as "an unstoppable force." President Trump also criticized the trade aspects of Johnson's Brexit deal.
