London | British Prime Minister Boris Johnson was set on Wednesday (AEDT) to make a fourth attempt to call a snap election, after Opposition Leader Jeremy Corbyn's Labour Party again stymied his effort to break the Brexit deadlock in a parliamentary vote late on Monday (Tuesday AEDT).

Mr Corbyn's Labour Party on Monday denied Mr Johnson the two-thirds majority that is legally required to call an election, saying the plan would leave open a theoretical chance of a no-deal Brexit. The election motion gained 299 votes, well short of the required 434.
