Scottish independence vote depends on sustained support, says UK minister

Alister Jack says government could allow vote if support for referendum stays above 60% for long period

The UK government could approve a second Scottish independence referendum if support for staging one stays above 60% for a sustained period, Alister Jack, the Scotland secretary, has said.

Jack said consistent support for a fresh vote would confirm to the government that one was justified, as he signalled a further softening of the Conservatives' previously rigid rejection of Scottish National party demands for a second referendum.
