Burnham v Swinney: will the UK PM overshadow the SNP’s conference?

UK Prime Minister John Swinney will present a new challenge for the Scottish National Party (SNP) at its conference this weekend.

His visit to Scotland will loom large over the event, which aims to reinvigorate the case for a second independence referendum.

Even former Labour MP Andy Burnham has been invited to the conference, highlighting the SNP's efforts to broaden its appeal.

The SNP is expected to use the conference to set out its stall for the upcoming general election.
