David Cameron has challenged the SNP to list specific examples of how the UK Government has failed to deliver on the vow made in the final days of the independence referendum campaign.
He hit back at the party’s Westminster leader Angus Robertson who asked – a year to the day the commitment was given – when the promises to the people of Scotland would be made good.
The Moray MP quoted Gordon Brown – described by Alex Salmond as the “Moses of the vow” – who has accused the Conservatives of “falling short” on delivery of the recommendations of the Smith Commission.
But Mr Cameron branded the SNP’s complaints on devolution “all bluster” and urged the party to stop talking about process and start outlining its plans.
He told Mr Robertson at Prime Minister’s Questions: “We said we would introduce a Scotland Bill, we introduced a Scotland Bill.
“We said unprecedented devolution on taxes, there’s been unprecedented devolution on taxes.
“We said we’d provide those welfare powers, we’ve given those welfare powers.”
Mr Robertson said only 9% of Scots believed the vow had been delivered and highlighted the Conservatives’ refusal to accept a single amendment to the Scotland Bill.
“Tory bluster and condescension will not go down well in Scotland,” he added, before putting his question a second time.
Mr Cameron said he had not given “one single example”, adding: “If you can point to a tax we promised to devolve but haven’t devolved, I’d accept it.
“If you can point to a welfare change we promised to devolve but didn’t devolve, I’d accept it, but you haven’t done those things.
“You give me a list of the things that were promised and not delivered; then we can have a very reasonable conversation.”
After PMQs, the SNP said the UK Government had ignored serious amendments to the Scotland Bill recommended by the cross-party Scottish Parliament devolution committee.
Mr Robertson insisted there were a “number of key areas”, including welfare powers, the constitution and employment, where the legislation fell “significantly short”.
Former first minister Mr Salmond said it was for the prime minister to answer the questions not ask them at the weekly session.
