Former Labour prime minister Gordon Brown says his think tank is going into campaign mode to stop independence GORDON Brown’s new plan to prevent Scottish independence and save the Union has been summarily dismissed by the SNP. The former prime minister unveiled a fresh strategy to prevent independence after pro-Yes parties won an increased majority in the Holyrood election. He announced his think tank, Our Scottish Future, will become a "campaigning movement" to make the "positive, progressive and patriotic case for Scotland in Britain". The group will make the case for a "reformed" UK, Brown said, and target "middle Scotland" – the 40% of Scots who he believes are not strongly committed to either the Union or independence.
