British finance minister Sajid Javid has postponed his first budget statement which he had been due to give on November 6 because of delays to Brexit and the government's attempts to call an early election, a Treasury source said on Thursday.

"Parliament has voted for a delay. We're calling for an election, so we won't be delivering the budget on November 6," said the source.
