MPs are to begin an inquiry into how any possible referendum on Scottish Independence would be handled.
They'll look at whether any referendum should be handled in London or Edinburgh, as well as who in Scotland should be eligible to vote for independence.
Their inquiry comes as Alex Salmond has announced that he will offer the Scottish people a referendum on introducing a separate tax and welfare system, a proposal which has been dubbed 'independence lite'.
The SNP won by a landslide in the elections to the Scottish Parliament in May - the first time any party gained an outright majority at Holyrood. The most recent opinion polls suggest 39% of people living in Scotland would vote yes in an referendum for full independence. 38% of respondents indicated they wanted to remain part of the UK.
Recently Alex Salmond outlined plans to reduce the voting age in Scotland from 18 to 16, a move seen by commentators as an attempt to increase the proportion of people who'd vote for separation from the UK .
It's thought that the government in London has no power to block this move, one which is unlikely to be mirrored in the rest of the United Kingdom.
The Scottish Affairs Committee at Westminster has announced the initial stages of the inquiry, and is inviting the public to send issues for consideration to them by the 18th of November.
Clarification: An earlier version of this story failed to note that the recent opinion poll on full Scottish independence put those in favour on 39 per cent, those opposed on 38 per cent.
