As I argued in The Sunday Telegraph at the weekend, it is a monstrous breach of trust. But – as our editorial in the March 8 issue of the Spectator says – there is still an opportunity for the Lords to act as the conscience of the nation and turn the Salisbury Convention on its head. By tradition, the Upper House does not reject a manifesto Bill at second reading, nor introduce a wrecking amendment to such Bills. In this case, the Lords have a moral responsibility to compel the Commons to enact the manifesto pledges its members were elected to implement. My conversations with peers in the past few days suggest that they are attracted by the idea – not least because it would dramatise the new assertiveness of the House of Lords – but that there is not yet a critical mass of support for such a measure. Time to apply some pressure, I reckon. What do Coffee Housers think?
