The Scottish first minister is to argue the country needs independence to stop unpopular policies being "imposed" by the UK government.
First Minister Alex Salmond has said that independence would give Scottish people the power to decide what kind of future they want for their country.
Alex Salmond will make the claim during the first in a series of summer speeches.
In a speech in the Highlands, he said a newly independent Scotland would recoup £50m in savings from the UK parliament and Whitehall.
He is expected to say that an independent Scottish parliament would be more cost-effective and more representative than Westminster.
He said Scottish voters' wishes would be truly reflected.
And he will launch a strongly-worded attack on the pro-Union campaign.
The Better Together campaign said Mr Salmond's vision of the future was not the best for young people and services.
The first minister wants Holyrood to have the power to reject Trident, Royal Mail privatisation and changes to the housing benefit system.
The first minister launched a strongly-worded attack on the pro-Union campaign.
Speaking at the Nigg Energy Park on the Cromarty Firth, he will argue that these policies were being imposed on Scotland despite a majority of Scottish MPs voting against them.
He wants Holyrood to have the power to reject Trident, Royal Mail privatisation and changes to the housing benefit system.
He will describe this as a "democratic deficit", reviving a phrase that became popular in the successful campaign for devolution.
Speaking at the Nigg Energy Park on the Cromarty Firth, he argued that these policies were being imposed on Scotland despite a majority of Scottish MPs voting against them.
Mr Salmond hopes it can help to persuade a majority of Scots voters to back independence.
Mr Salmond said: "The political union does not work for Scotland any more. It holds Scotland back and imperils our future. It will not bend and it will not change of its own accord.
The first minister will say that while he seeks to end Scotland's political union, he wants to keep other ties such as a currency union, a social union and the Union of the Crowns.
"So we will, we must, change it. We must address and fundamentally change the political and economic union as a matter of urgency."
He will also describe leaders of the pro-Union campaign as a "parcel o' rogues" - a reference to a song written by Rabbie Burns.
He also praised the work done to revive the fortunes of Nigg, a former North Sea oil and gas fabrication yard.
Mr Salmond is expected to say: "Scare stories give way to reason, and hope will always trump fear."
New jobs have been created at the site to work on contracts for the oil and renewable energy sectors.
He will add: "Recently the parcel o' rogues in the No campaign have been caught out big time in the nature of their arguments.
Mr Salmond added: "It is really great to be back at Nigg when this place is being restored to its proper position as beating industrial heart of the Highlands of Scotland."
"They claimed that mobile phone charges would go up in an independent Scotland the day before the European Commission set about abolishing roaming charges across Europe.
A spokesman for Better Together said Mr Salmond's vision for Scotland was "not about what is best for our young people, our public services and our pensions".
"They said that the UK's triple-A status was crucial to Scotland and then proceeded to lose it for the UK.
He added: "It is only about realising his long held ambition of separating Scotland from our closest neighbours.
"They said that UK embassies would no longer promote whisky, oblivious to the fact that they already charge for such receptions.
"We will work every day between now and the vote to ensure that we stay United with our friends, families and workmates."
"All of this nonsense and much, much more is wrapped up in what the Better Together campaign themselves describe as 'Project Fear' - their confidence that they can scare people out of voting for independence."
'Nuclear weapons'
His address comes the day after former chancellor Alistair Darling, who is leading the Better Together campaign, set out what he described as a "powerful, principled and positive case for remaining in the UK".
Mr Salmond is expected to point out that Scottish taxpayers spend more than £50m a year towards the running of the Houses of Parliament and the Scotland Office in Whitehall.
He will also focus on the proposal to award Westminster MPs salary increases of more than £6,000 a year.
Mr Salmond is expected to say: "At a time of severe economic constraint it is simply unacceptable for parliamentarians to receive such substantial increases to their salaries when families and individuals are facing unprecedented austerity.
"We don't need to spend £50m-a-year on a political system that simply doesn't deliver for Scotland. Despite a majority of Scottish MPs voting against Bedroom Tax, Child Benefit cuts or the housing of nuclear weapons our shores - we still have these measures imposed on us.
"With independence we invest in ourselves - and deliver a far more cost effective, transparent and representative parliament that truly reflects the wishes and expectations of the people we are honoured to represent."
Mr Salmond will also defend the SNP's record in government and call for more powers for Scotland.
