French President Emmanuel Macron has rejected Boris Johnson's demands to renegotiate Britain's Brexit deal, insisting that the terms of the current agreement are "indispensable."

Axar.az reports citing Businessinsider the British Prime Minister told Macron that the UK parliament would never sign up to a deal which contains the controversial Northern Ireland backstop agreement, which is designed to prevent a hard border with Ireland after Brexit.

However, Macron insisted that any renegotiated deal would have to retain the backstop.

The exchange came after the German Chancellor, Angela Merkel suggested that a solution to Britain's Brexit crisis could be found in the next "30 days."

Johnson today praised Merkel's "can-do spirit."

"She said if we can do this in two years then we can do this in 30 days and I admire that 'can-do' spirit that she seemed to have and I think she is right," Johnson said.

"I think that the technical solutions are readily available and they have been discussed at great length."
