Scotland's First Minister Alex Salmond addressed the SNP conference in Aberdeen as the Yes campaign gains momentum.
In his latest blog our Political Editor, Peter MacMahon, looks back at the SNP's history and their biggest challenge to date.
The boss of Scotland's largest industrial company tells ITV News he believes Scottish independence would bring "real costs" for business.
Thousands of defence jobs will be at risk if Scotland votes for independence in September, according to Defence Secretary Philip Hammond.
Mr Hammond warned workers at the Glasgow-based firm Thales that their future prosperity, and that of their families, would be put in jeopardy by a Yes vote for independence.
He said: "The creation of a border between this facility and its largest customer will put at jeopardy the future prosperity of this business, the people who work in it and their families and dependents."
"If we were to separate, then the future of the defence industry in Scotland that depends on MoD orders will be put at risk," he added.
Scottish independence would "weaken" the effectiveness of the Royal Navy and damage "the very heart" of Britain's maritime defence forces, the First Sea Lord has warned.
A Yes vote would harm "the security" of Scotland and the rest of the United Kingdom, Admiral Sir George Zambellas told The Telegraph.
He said an independent Scotland’s claim on the Royal Navy would "greatly weaken the carefully evolved 'whole', as bases, infrastructure, procurement, spares, personnel and training face a carve up”.
“I believe that independence would fundamentally change maritime security for all of us in the United Kingdom and damage the very heart of the capabilities that are made up of the Royal Navy, the Royal Marines, the Royal Fleet Auxiliary and the Fleet Air Arm," he added.
Alex Salmond "failed to provide voters with the real facts and costs of separation" following his speech this afternoon, said the Scottish Conservatives.
The party's chief whip John Lamont also attacked Mr Salmond's bid to woo more female voters with the promise of more women in his party, saying, "Alex Salmond knows he has a problem appealing to half of the electorate, but women can spot a dodgy chat up line when they hear it."

Experts said Alex Salmond must deliver the speech of his life today, but he fell far short of appealing to people beyond die-hard Nationalists.
This was what we have become used to from the First Minister - full of assertions and repeating the same, tired divisive rhetoric of how everything is Westminster's fault.
It was gripe and grievance politics without giving the people of Scotland the real facts or costs about independence.
Responding to the First Minister's speech, former Liberal Democrat leader Sir Menzies Campbell said:
All we have heard today is more of the same from a party who seem reluctant to answer the big questions over what independence would truly mean for Scotland.
The one thing the polls show is that the majority of Scots want to stay as part of the UK family with a stronger Scottish Parliament.
Most Scots want to see us build on the successes of devolution and secure new powers for Holyrood.
That is what Liberal Democrat Home Rule plans would mean for Scotland.
A positive vote to stay in the UK will help us deliver the change that people really want to see.
Margaret Curran, Labour's shadow Scottish secretary, said: "No one will be taken in by Alex Salmond's speech."
"Nothing is more negative than his message that Scots should break up the country we have built over three centuries and turn our back on our neighbours," she went on.
In response to Mr Salmond's announcement of an increase in female representation in his cabinet, she said: "Women will see through his cynical attempts to win them over. Women's rights have improved during my lifetime because of, and not in spite of, Scotland being part of the UK."
"Labour led the way on delivering rights for women," she added. "Now even Salmond's own officials admit that he has no policy on childcare and his figures don't add up."
"The message to the people of Scotland is clear. Vote no and you have a chance of getting reality back rather than this drivel from Alex Salmond."
Scottish First Minister Alex Salmond told ITV News "the finishing line is not going to be reached by statistics, it's going to reached by winning the argument" over Scottish independence

There are many different colours and threads woven into the Scottish tartan and all must be celebrated we need to mobilise all of the talents and all of the potential of all of our people and we have to reflect that in how we will proceed after September 18th and the approach we will take to bring Scottish together as we attempt to move forward.
...In March 2016, Scotland will become an independent country and join the international family of nations.
Scottish First Minister Alex Salmond poked fun at Lord Robertson's comments that a Yes vote for independence would be welcomed by the “forces of darkness” at his address today, joking that the "Daleks ain't too happy".
He called the No campaign, "totally laughable and completely ludicrous."
Thee 'No' campaign is "miserable, negative, depressing and the most thoroughly boring campaign in political history," he added.
