Boris Johnson has set himself on course for a constitutional clash with Nicola Sturgeon if she pushes ahead with plans for a second Scottish independence referendum - which the PM has called 'irresponsible and reckless'.
Counting continues in the Scottish parliamentary contest, with the SNP leader's hopes of achieving a majority on a knife edge, after a poll predicted the party could miss out by just one seat.
But it is still highly likely the SNP will win its fourth term in power at Holyrood, and Ms Sturgeon said 'when the time is right' she will offer Scots 'the choice of a better future' in a second independence referendum.
