"Your (Boris Johnson's) letter contains a downright lie. Neither Mr Salmond nor Ms Sturgeon ever made a "personal promise" - Mr Salmond made clear repeatedly that he was merely expressing a "personal view". It was not in the gift of either leader to close off the democratic rights of citizens. You, however, *have* contravened a solemn undertaking made by your political party as part of the post-referendum Smith Agreement. You accepted that the people of Scotland were free to choose independence in the future. Now you say the UK is a prison for the next 50 years. The idea that the people of Scotland would have consciously voted for 50 years of dictatorship in 2014 if they had believed that was on the ballot paper is as ludicrous as it is offensive."
