First Minister Alex Salmond yesterday called on Gordon Brown to clear the way for a raft of new powers to be devolved to Holyrood this year.
This is despite these being rejected by MSPs at Holyrood last week.
The SNP say a range of measures from the Calman Commission on devolution should be implemented as soon as possible in areas like drink-driving, speed limits, air guns and electoral administration.
“It is time to seize the moment – not let the Calman report gather dust,” a spokesman for Mr Salmond said yesterday.
The Nationalists say there is consensus on these measures, as well as controlled substances in the treatment of addictions, being devolved.
“The first minister will write to the prime minister this week seeking agreement on the way forward during the recess period,” the spokesman added.
“The necessary orders could then be formally tabled after the recesses and the measures enacted before the end of the year.
“The Calman Commission spent over a year deliberating, and published a report with the support of all three Calman parties, containing specific proposals for improving the governance of Scotland which everyone agrees with.
“Therefore, people will be understandably puzzled if rapid progress is not made.”
The Scottish Government says the new powers could be fast-tracked through via legislative orders at both Holyrood and Westminster.
Mr Salmond is sending a copy of the Scottish Parliament orders drawn up by the Scottish Government last week.
But Holyrood last week rejected the moves when Constitution Minister Mike Russell called for them to be adopted in an amendment after MSPs debated the Calman report. All three opposition leaders – Iain Gray of Labour, Tory chief Annabel Goldie and Lib Dem Tavish Scott – later branded the government move a “stunt”.
The SNP have refused to join the steering group on implementing Calman’s recommendations because they disagree with tax proposals.
