Both sides in the Scottish independence referendum debate have seized on a pledge by the three main Westminster parties to devolve more powers.
The pledge, signed by David Cameron, Ed Miliband and Nick Clegg, also promises equitable sharing of resources and preserving the Barnett funding formula.
The “Yes” campaign described it as an “insult” to voters and asked why it had taken so long to offer.
“Better Together” said it was “a vision around which Scotland can unite”.
Labour leader Ed Miliband and former Prime Minister Gordon Brown are on the campaign trail for Better Together. Mr Brown accused The SNP are “perpetrating a lie” about protecting the NHS.
The pledge signed by the Conservative, Labour and Lib Dem leaders appears on the front of the Daily Record newspaper.
The first part of the agreement promises “extensive new powers” for the Scottish Parliament “delivered by the process and to the timetable agreed” by the three parties.
The second says the leaders agree that “the UK exists to ensure opportunity and security for all by sharing our resources equitably”.
The third “categorically states” that the final say on funding for the NHS will lie with the Scottish government “because of the continuation of the Barnett allocation for resources, and the powers of the Scottish Parliament to raise revenue”. The Barnett formula is the method used to determine the distribution of public spending around the UK.
Shadow Foreign Secretary Douglas Alexander, speaking for Better Together, denied the powers pledge had come too late in the referendum debate.
Speaking on BBC Breakfast, he said: “Here in Scotland, we have been talking about these powers for many months. What we are saying today is we can have the best of both worlds. We can have a stronger Scottish parliament but with the strength, stability and security of the United Kingdom. “That pledge, that vow that we can have faster, safer, better change is actually a vision around which Scotland can unite.”
