British Prime Minister Boris Johnson has likened himself to The Incredible Hulk, saying "the madder Hulk gets, the stronger Hulk gets" as he stressed his determination to take Britain out of the European Union with or without a deal on October 31.

The Mail on Sunday newspaper reported that Mr Johnson said he would find a way to circumvent a recent parliamentary vote ordering him to delay Brexit.

"Hulk always escaped, no matter how tightly bound in he seemed to be — and that is the case for this country. We will come out on October 31," he said.

British MPs have repeatedly rejected the exit deal Mr Johnson's predecessor Theresa May negotiated with the EU, and this month rejected leaving without a deal on October 31.

Last week, Mr Johnson was forced to deny lying to the Queen after a Scottish court ruled that his decision to suspend Parliament until mid-October was illegal.

Mr Johnson has said he wants to negotiate a new deal that does not involve a 'backstop', which would potentially tie Britain to EU rules in order to avoid checks on the border between Ireland and Northern Ireland.

The EU has so far insisted on the backstop, and Britain has not presented any detailed alternative.

Nonetheless, Mr Johnson said he was "very confident" ahead of a meeting with European Commission President Jean-Claude Juncker on Monday.

"There's a very, very good conversation going on about how to address the issues of the Northern Irish border. A huge amount of progress is being made," Mr Johnson told the Mail on Sunday, without giving details.

"Banner might be bound in manacles, but when provoked he would explode out of them," he said.

Earlier on Saturday, former Conservative minister Sam Gyimah said he was switching to the pro-EU Liberal Democrat party in protest at Mr Johnson's Brexit policies and political style.
