Matthew d’Ancona thinks that Gordon Brown may have some genuinely Big Ideas.

Stand by for a huge constitutional debate: that was one of many messages to be drawn from Gordon Brown’s launch this morning. Asked whether his plans included a written constitution, he would only say that he favoured a “better constitution”. But there was an explicit promise to curb the Crown prerogative, make Parliament more powerful, submit certain government appointments to parliamentary oversight, and (less overtly) entrench citizens’ rights and responsibilities in some way. Gordon left us is no doubt that he is thinking big.

Meanwhile, over on OpenDemocracy.net, Anthony Barnett sets out a list of what a new constitutional settlement would have to cover.
