Mr Rennie says there would be "blind panic" if Scotland had become independent, given what he said was the SNP's reliance on oil prices.

What would happen if the Scottish Parliament got full fiscal autonomy? Excuse the jargon. What it means is that Holyrood would have control over all of taxation in Scotland......

Ms Sturgeon asked about "full fiscal autonomy" (complete of taxation and spending) for Scotland. She says she would vote for it. Mr Murphy says he doesn't support it, because it means being cut off from sources of taxation across the UK.
Ms Sturgeon says the country has to work towards boosting renewable energy sources.
Mr Harvie says you can't save money by "cancelling your membership of the civilised world".
Mr Murphy says the Conservatives refuse to tax millionaires more, while Labour wants to end "zero hours" contracts.
