The First Minister compared it to the Poll Tax as a symbol of why devolution was needed.
Is the parallel correct or is it opportunism while the UK government's welfare policies are causing hardship and resentment?
The campaign for devolution was long established before the Poll Tax and 10 years previously Scotland voted in favour of home rule, to be thwarted by the 40% rule.
The similarity is that the 'bedroom tax' like the Poll Tax is increasing the unpopularity of a UK Conservative Government in Scotland.
The Poll Tax did indeed contribute to Thatcher's downfall, but at the hands of her own party only for her successor John Major to win the next election then ditch it.
Labour hope for a similar outcome, but with Ed Miliband replacing Cameron in 2015 to then ditch the tax. By then, however Scotland could be in independence talks if it's a Yes vote next year.
Alex Salmond also drew parallels, between the pre-devolution period and the present, citing Tory warnings it wouldn't work and would damage Scotland. While there may be some similarities between the Poll Tax and bedroom tax there are differences between pre-devolution and the present period.
Support for a Scottish Parliament was more established among the public and it was Westminster who needed to be convinced. This time, according to almost all the polls and despite the huge SNP victory in 2011, it is the people who still remain to be persuaded.
The natural majority for independence doesn't currently exist. However following the 2011 polls defying victory no-one in the No campaign would think their job is done.
A referendum is different to a General Election, where resources are targeted at marginal seats and swing seats where the contest is won and lost.
In this every single vote counts, so the undecided voters become the focus of the campaigners. Over the next year the politicians and campaigners from both sides of the argument will seize on every opportunity they see to persuade voters to back their position.
It is not about changing people's minds anymore but all about the undecideds waiting to be convinced. For those yet to commit one way or another it is essential they have their questions answered to allow an informed choice. We need to be involved and informed and challenge the politicians.
Some of the campaigners think it is a contest to be won by one side or the other. It's not. It is a decision for the people.
It's your country, your future, your vote. Not theirs.
