Leaders of the three main parties pledged their support to the devolution of greater powers in an effort to bolster the pro-unionist campaign ahead of Scotland's referendum on independence on September 18.
In a joint statement made Tuesday in Edinburgh, Scotland's Conservative leader Ruth Davidson, Labour leader Johann Lamont, and the Liberal Democrat leader Willie Rennie, urged voters to back the call for more powers, instead of independence.
"It is possible to vote 'No' on 18 September and also say you are voting for change, for more powers for the Scottish Parliament," said Lamont.
Labour leader Ed Miliband urged people across the UK to fly the Scottish flag, the Saltire, as a mark of support for keeping Scotland within the British union.
“Over the next few days we want cities, towns and villages across the UK to send a message to Scotland: stay with us,” he said.
The frantic moves by unionist parties come after polls put the Yes campaign ahead, two weeks before the vote.
Buckingham Palace meanwhile put an end to speculation the Queen will get involved in the debate in the run up to the referendum, after press reports that suggested she was concerned about the breakup of the union.
A spokesperson said the referendum was "a matter for the people of Scotland".
"The sovereign's constitutional impartiality is an established principle of our democracy and one which the Queen has demonstrated throughout her reign.
"As such the monarch is above politics and those in political office have a duty to ensure that this remains the case.
"Any suggestion that the Queen would wish to influence the outcome of the current referendum campaign is categorically wrong.
"Her Majesty is firmly of the view that this is a matter for the people of Scotland."
Scottish leader Alex Salmond said he met the Queen two weeks ago, but did not disclose what was discussed.
"I want the Queen as head of state, as Queen of Scots of an independent Scotland, as her ancestors were," he said.
"I think Her Majesty the Queen, who has seen so many events in the course of her long reign, will be proud to be Queen of Scots, and indeed we would be proud to have her as monarch of this land."
