Why has the election been called now?

Less than 24 hours after Rishi Sunak's surprise election announcement, we look ahead to the parties' campaigns. What has been the fall out? How have Labour responded to the shock news? And why didn't Rishi have an umbrella?

James Heale is joined by Isabel Hardman and former Labour adviser John McTernan to discuss.
