The European Union (Withdrawal) Bill returns to the Commons today for consideration of the numerous amendments made during its eventful passage though the Lords. Some commentators have accused the Lords of exceeding their constitutional authority, with the Salisbury convention being cited in defence of this position. David Beamish discusses how the convention operates and argues that the Lords have not breached it so far.

The European Union (Withdrawal) Bill has prompted much discussion of the role of the House of Lords in passing legislation, including references such as this to the Salisbury convention:

That passage, from an article in The Times by Matt Ridley, who sits in parliament as an elected hereditary peer, relates to the amendments made by the Lords to the Withdrawal Bill and in relation to the proposal for a ‘Leveson Two’ inquiry. A day later, Iain Martin wrote in The Times:
