Two days have been set aside for the European Union (Notification Of Withdrawal) Bill's second reading debate - the first time the upper chamber has been given a chance to debate the legislation.

Before the debate Labour and Liberal Democrat peers indicated they were prepared to table amendments, including to ensure a guarantee for EU citizens' rights and the ability of Parliament to have a meaningful vote on the final Brexit deal.

However, support for House of Lords reform is predicted to increase if peers obstruct or delay Brexit, new research claims.

An ICM survey for Change Britain, which campaigns on the terms of Brexit, found 43% of respondents are more likely to back abolition or reform compared to 12% who are less likely in such circumstances.
