Miliband plea for political reforms
Ed Miliband has called for a constitutional convention to address demands for wider devolution of power thrown up in the wake of the Scottish independence referendum.
The Labour leader said there needed to be a series of regional "dialogues" covering every area of the UK on how power could be dispersed from Westminster - including in England.
Among the issues he said should be considered are the reforms that would be needed at Westminster as more power is devolved to Scotland - including the case for a "senate of the nations and regions" or for codifying the constitution.
"The Labour Party will not now sit back and put up a 'business as usual' sign over Westminster. Nor will I allow this moment to be used for narrow party political advantage," he said.
"We need a response that matches the scale of this moment. That starts with delivering on our promise of further powers to Scotland.
"But other people in Britain, including England, now deserve the chance to shape their own futures with a dynamic devolution settlement."
Labour said that over the coming weeks the party would be setting out plans for a series of regional debates bringing together MPs and councillors with ordinary citizens and civil society.
Under Labour's plans, each region would then draw up a series of recommendations that would be considered at a constitutional convention to be held in the autumn of 2015, after the general election.
"What is needed is a comprehensive and credible process involving citizens, to take forward a debate about how we are governed," Mr Miliband said.
"These issues can no longer be fixed solely by politicians or prime ministers trying to shore up their position in their own party. The people need to be given a voice too."
