The same series of events. Two different and contradictory accounts. How can both be true? For the most part the events themselves are not in dispute. Some details such as dates and times may be disputed. But mostly the events are a matter of public record and accepted by both sides. The argument is over whether the events involved the kind of orchestration that would amount to a conspiracy. Alex Salmond sees that level of orchestration. Nicola Sturgeon does not.
