LONDON (Reuters) - Prime Minister Boris Johnson will try to drive the legislation needed to take Britain out of the European Union through parliament in the next 9 days, or else break his "do or die" pledge to leave on Oct. 31.

Johnson was forced on Monday to abandon his attempt to have a straight 'yes or no' vote on his Brexit deal, and is instead trying to speed through the legislation for Britain to leave the EU through the lower and upper houses of parliament.
