The debate over Scottish independence gets underway tonight with the first live television clash between the First Minister and the man leading the campaign to keep the UK together.
Alex Salmond will take on former chancellor Alistair Darling, the chair of the pro-UK Better Together group, in a two-hour long TV debate programme this evening.
There are now just over six weeks to go until voters in Scotland decide whether to remain in the UK or become an independent nation in the September 18 referendum.
Polls have so far failed to show a majority in favour of independence, but both campaigns are hoping to to receive a boost in support as a result of tonight's TV debate.
The first debate between Alistair Darling and Alex Salmond had barely finished when their respective teams went into battle.
Campaign rivals Alex Salmond and Alistair Darling both traded blows in a surprisingly feisty televised debate on Scottish independence.
Alistair Darling is getting 'feisty' during the STV Debate.
