Ed Milliband has raised the question of the need for a Constitutional Convention and the question of a written constitution.
He has also indicated that this is a matter for the people to engage with and potentially decide.
This is to be welcomed.
The starting point for the debate has to be a recognition that no form of devolution of powers within Britain has meaning or effect as long as Britain as a whole is governed by the European Union, subsidising it by £1 billion a week in payments and a £1 billion a week trading deficit.
The other key starting point is the recognition that Britain is not a United Kingdom of four nations.
Britain is a whole nation comprising of Wales, Scotland and England. We have in reality two official languages, English, massively the most prevalent, and Welsh, spoken by a significant number. Gaelic is not an official language and is spoken by around 1% of the population in Scotland.
