MPs are expected to vote on eight clauses and amendments this evening, with two of them likely to grab the headlines.

Conservative whips are most concerned about new clause 57, an amendment tabled by Labour back-benchers which requires the Government to guarantee the rights of EU migrants before Article 50 is triggered.

Around 10 Tory MP are expected to defy the Government's three line whip and vote in favour of the amendment. Some of them have European spouses so have a personal interest in the amendment.

The other significant vote is likely to be around amendment 43, which has been tabled by the Liberal Democrat which requires a second EU referendum before Britain leaves the EU.

The clauses and amendments will be voted on before the main business of the evening - the vote on whether Article 50 itself should be triggered.
