John Swinney expected to lead Scotland after taking the helm of the Scottish National Party

LONDON (AP) — Scotland’s former deputy first minister was poised to become its third leader in just over a year after taking the helm of the troubled Scottish National Party on Monday.

John Swinney, who led the SNP two decades ago, was the only candidate to replace First Minister Humza Yousaf as the leader of the party.

The SNP has been in turmoil since long-serving First Minister Nicola Sturgeon abruptly stepped down last year during a campaign finance investigation that eventually led to criminal charges against her husband.
