Is Constitutional Convention on the cards if Scots vote no?

If Scotland votes 'no' in its independence referendum, it's abundantly clear that its parliament and government will get significantly enhanced powers in the months and years to come, even if it's not entirely clear what those powers will be.

But what about Wales and the other nations, England and Northern Ireland?

I understand that David Cameron has been taking soundings about a constitutional convention to work out a way forward for the United Kingdom in the event of a 'no' vote on Thursday.

Constitutional conventions are used to work out future arrangements for government at times of crisis or when confidence has been lost in the current systems.

Ireland's Constitutional Convention, for example, was set up following the country's financial crisis. It's made up of nominated politicians and members of the public chosen at random.

If the Prime Minister is seriously planning to hold such a convention for the UK, it would be something of a vindication for the Welsh First Minister Carwyn Jones who has publicly called for one for some time, although his opponents criticise him for not formally doing anything to make it happen.

As far as I know, there haven't been any formal or informal approaches to Carwyn Jones but then his support is well-known.

But it is perhaps another sign amongst many in the last couple of weeks of how seriously the way the UK is governed is being taken by party leaders who've sometimes been accused of not taking the aspirations of the UK's nations seriously enough.
