Britain's Parliament will get to debate and vote on any final Brexit deal relating to the withdrawal process.
The UK's Brexit Secretary David Davis has told the House of Commons the agreement will only hold if Parliament approves it.
He announced a Bill this afternoon (Monday) covering areas including citizens' rights, the divorce payment and a transition period.
The decision to give a binding vote to MPs is seen as a concession to pro-Europe rebels in Prime Minister Theresa May's Conservative Party.
