Former prime minister Gordon Brown says he’s “not afraid” of another referendum on Scottish independence, though he does not believe one will take place soon. As he launched a renewed campaign to keep Scotland in the UK, he announced former Scottish Green Party co-convener Robin Harper would be on one of his organisation’s commissions. Mr Brown’s Our Scottish Future think tank will become a “campaigning movement” which seeks to appeal to “middle Scotland” – those who are not entrenched in their positions on the union or independence. The group is setting up a number of commissions which will examine how greater co-operation around the UK will benefit Scotland on issues such as health, poverty, the environment, and jobs.
