The normal period of purdah before Westminster and Holyrood elections is 28 days and applies to all ministerial announcements, so the Government cannot be seen to be attempting to buy votes with new spending policies.
But Holyrood's Referendum Bill Committee has heard the traditional rules do not go far enough when it comes to the significance of the referendum campaign next year and that purdah should also be extended to a broader range of publicly funded agencies.
According to a YouGov poll commissioned by the SNP, Scots prefer by 66% to 19% the idea of retaining the pound as the currency of an independent Scotland. Of those asked, 15% were undecided about which currency they would like to use in the event of a Yes vote next year.
The poll of just over 1000 voters, carried out over the first three days of the month, asked the question: "Do you think an independent Scotland should or should not keep the pound?"
