YES Scotland has been ­criticised for delaying publication of its donor income.

The pro-independence movement intends to wait a full year since its last disclosure before revealing who has been bankrolling it and how much they have given. Yes Scotland last revealed its donor list in April last year.

Yes Scotland had been expected to update its donor information four weeks ago, when its pro-union rival Better Together updated its list. Yes Scotland has previously called for both to release the details together.

However, after Yes ­Scotland's board met last week, it was agreed not to release the next donor figures until March or April.

Sir Alistair Graham, former chairman of the Committee on Standards in Public Life, said it was "anti-democratic" to keep voters in the dark about who was funding Yes Scotland.
