Scottish Labour’s leader faces uphill task to drive SNP off course

Anas Sarwar is challenging Nicola Sturgeon - the first time in British politics that two major party leaders have contested the same seat

Even with her face mask on, Mhairi Hunter is spotted by Asif, a business graduate rushing past with a shopping bag. You're that SNP councillor," he shouts, before tracking back to offer an impassioned one-man party political broadcast in support of the Scottish National party.

The focus of his wrath is Anas Sarwar, the Scottish Labour party leader, who is fighting Nicola Sturgeon for the Holyrood constituency of Glasgow Southside, one of Scotland's most ethnically diverse areas. Sarwar grew up nearby and his predecessors once took it for granted that Punjabi Glaswegians like Asif and his parents would vote Labour. But no more.
