London: British Prime Minister Boris Johnson has compared himself to the Hulk in a newspaper interview emphasising his determination to take Britain out of the European Union on October 31.

Johnson faces considerable legal and political hurdles, but told the Mail on Sunday he will meet the Halloween exit deadline regardless.

"The madder Hulk gets, the stronger Hulk gets," he told the tabloid, invoking the comic book and film character known for formidable but destructive strength.

Johnson remains defiant even though the British Parliament has passed a law requiring him to seek an extension to the deadline if no deal is reached. He has also lost his working majority in Parliament and been told by Scotland's highest court that his decision to suspend Parliament was illegal.
