An increasingly bitter split between the SNP and the Greens has brought even more Scottish parliamentary seats into play for Keir Starmer, Labour figures believe, amid a desperate fight by the first minister, Humza Yousaf, to stay in power.
Yousaf has already refused to rule out a Holyrood election as he faces damaging no-confidence motions this week. On Saturday he wrote to the leaders of Scotland’s political parties in an attempt to find “common ground” following his decision to axe a coalition with the Scottish Greens that had propped up his government. Yousaf maintained that it would be a “poor choice” for the Greens to back a no-confidence motion in his minority government.
