It has been an unexpected week in Scottish politics.
Nicola Sturgeon has been at the forefront of public life in Scotland for more than 20 years. Despite our profound disagreements, that is an incredible achievement.
In fact, the first time that we met was when she was standing against my Dad and I was just 12 years old. Although I’m not sure she’ll appreciate that reminder, it is testament to the service that she has given Scotland.
