Labour has claimed that pensioners would lose out under SNP plans for Holyrood to control taxation and spending in Scotland.

Party leader Ed Miliband said there would be a black hole in Scotland's budget. In response, SNP leader Nicola Sturgeon accused Labour of desperation and smear tactics.

The Conservatives and Liberal Democrats said the SNP was trying to enact a form of independence by the back door.

BBC Scotland's political editor Brian Taylor reports.
