Keir Starmer has officially launched his Labour leadership campaign in Manchester. Speaking at the Mechanics Institute, the shadow Brexit secretary said: "We need to fight to regain our heartland seats, not just those lost in this election, but the ones lost in previous elections." Sir Keir also highlighted the need for a "strategy for Scotland" where Labour went down to one MP in the 2019 General Election. Report by Jonesia.
