LONDON (Reuters) - Britain’s opposition Labour Party will vote in favor of three alternative Brexit options in parliament on Monday, including a proposal for a customs union and one for a confirmatory referendum on any deal, its Brexit spokesman Keir Starmer said.

The third option it will back, when lawmakers vote to try to find a majority for an alternative way forward, calls for an enhanced Norway-style deal which would include membership of the EU’s single market as well as a customs arrangement with the EU.
