Scots are being urged to sign a petition calling on the Westminster parties to deliver more powers for Holyrood and send a signal "rejecting any Tory strings" on the deal.

Former prime minister Gordon Brown said more than 105,000 people had already put their names to the petition, demanding that David Cameron honour the vow to transfer more powers that was made in advance of the independence referendum.

In a bid to attract more support, a street stall where people can sign the petition is being set up in Cowdenbeath, Fife, this morning.

Speaking ahead of the event, Kirkcaldy and Cowdenbeath MP Mr Brown said: "I urge both Yes and No voting Scots to sign the petition on the vow of a stronger Scottish Parliament to send a signal rejecting any Tory strings attached, now or later, to the delivery of the pre-referendum promises of more extensive devolution.

"The issue is not whether we have change or not: change is guaranteed. The question is whether it comes with strings attached qualifying the original promises."

The street stall will be opened by local Labour MSPs Alex Rowley and Jayne Baxter.

Mr Rowley said: "My belief is that No voters understand that we will do everything in our power to ensure that the change that they voted for is delivered with no damaging conditions attached.

"My conviction is that Yes voters will also want to support this effort to ensure that the promises made are promised enacted intact at the earliest opportunity."

Ms Baxter said: "Our goal is to unite Scotland within the UK by delivering the promises intact.

"The last thing we want is to allow Scotland to be distanced from the UK by relegating the role of Scottish representation at Westminster."

SNP MSP for Mid Scotland and Fife Annabelle Ewing said: "In the run up to the referendum, the vow that the Westminster leaders made was for extensive new powers for Scotland. The Scottish people fully expect this to be delivered - and will accept nothing less.

"The fact that Gordon Brown is now having to go round the country asking people to sign a petition holding Westminster to account for something he promised was a done deal speaks volumes. You couldn't make it up.

"45% of people voted for independence, and the No campaign told the 55% who voted No that they were voting for home rule.

"Scotland is waiting on Westminster to deliver the powers we need to build a fairer, more equal country. Tory talk of three year delays and holding Scotland to ransom over English votes for English laws will not wash. Independence would have been delivered in 18 months - Westminster made a promise to the people of Scotland for 'faster' delivery of substantial new powers and they must now honour it."
