Alex Salmond has called for a "united" pro-independence campaign that sets aside differences between parties.
The Alba leader - who quit the SNP in 2018 - said Nicola Sturgeon's party was unlikely to win a majority of votes cast in Scotland at a general election on its own.
He pointed to the 2015 UK poll which saw a Nationalist landslide in terms of seats won - but only achieve 50 per cent of the total votes.
