Scottish finance minister John Swinney has responded to Standard Life's revelation that they would relocate parts of its operations to England if an independent Scotland "were to threaten" its business:
One reporter asks why Scottish voters should trust that the SNP will deliver on its independence pledges.
Salmond says that the SNP's election success to date shows that people trust it to deliver on its vision.
He says people should read the White Paper to see the level of detail it has gone into to describe how independence would work.
SNP leader and Scottish First Minister Alex Salmond congratulated Mr McDonald on a "fantastic SNP win", adding he would be a "first-class representative for the people of Donside".
The by-election was held following the death in April of Nationalist MSP Brian Adam, who had been suffering from cancer.
Mark McDonald said that by winning the seat he had "protected the legacy of the late Brian Adam, who was a great mentor to me and a great friend of mine".
He added: "We worked hard, we put up a good campaign on the issues that mattered to the people of Aberdeen Donside. We wanted to make sure we protected the legacy of Brian Adam.
"Our objective was to win the seat, now we've won the seat the hard work starts."
The Scottish National Party has won the Aberdeen Donside by-election, but with a greatly reduced majority.
Mark McDonald won the seat after polling 9,814 votes, just over 2,000 more than the Labour candidate who was his nearest rival in the contest.
However the SNP's majority fell by more than 5,000 votes from the result in the 2011 Scottish Parliament election.
- Mark McDonald (SNP) 9,814
- Willie Young (Labour) 7,789
- Christine Jardine (Liberal Democrat) 1,940
- Ross Thomson (Conservative) 1,791
- Otto Inglis (UKIP) 1,128
The Scottish National Party has held Aberdeen Donside in the by-election, with Mark McDonald elected as the MSP for the constituency.
Scotland has generated more tax revenue per head than the UK as a whole every year for the last three decades, SNP deputy leader Nicola Sturgeon will tell her party today.
Speaking at the SNP conference in Inverness, Sturgeon will say that tax receipts from Scotland were £1,676 higher per head in comparison to the UK as a whole in 2011/12.
"Scotland can afford to be independent and don't let anyone tell you different.
"For every one of the last 30 years we have generated more tax revenue per head than the UK as a whole. Every single one of the last 30 years.
"If there is one fact I want you to remember over the next 18 months and tell everyone you know, it is this one.
"During those 30 years, oil prices will have gone up and they will have come down.
"The economy will have grown and it will have been in recession.
"But one fact has remained constant. In every single one of those 30 years tax receipts per head of population in Scotland have been greater than tax receipts per head of population in the UK.
"How dare any unionist politician say that Scotland doesn't pay her way."
First Minister Alex Salmond will set out his case for why Scotland would be better off if it was independent from Britain in his speech at the SNP spring conference today.
The event comes just two days after he said that voters in Scotland will decide the country's future in an independence referendum to be held on September 18 2014.
Mr Salmond promised the conference would "set out the 'why of independence' to the people - what won't happen in an independent Scotland will be getting dragged into illegal wars, having Trident nuclear weapons dumped on the Clyde for another 50 years, or the imposition of bedroom taxes.
"And what will happen will be the mobilisation of the human and natural resources of Scotland to build a prosperous economy and just society."
