Britain's upper house is getting ready to put the government's Brexit bill under scrutiny.

The House of Lords will be debating the bill tomorrow.

Former Labour Cabinet Minister Lord Mandelson has said he doesn't want the towel thrown in too early.

UK correspondent Juliette Fletcher told Andrew Dickens what that means.

"Basically he wants to make sure that there's a final vote on the deal before Britain leaves the EU. He wants any leave campaigners who are having second thoughts to have the chance to vote again."
