Sunday looms for Labour MPs to elect new Prime Minister

Sunday is decision day for Labour MPs choosing a new Prime Minister. Under a rule introduced in 2021, if the party is in power at the time its leader vacates the job, the caucus can elect a new one as long as they have a two thirds majority. Otherwise the decision goes to the wider party membership and unions. Former Labour MP and Chief party whip and former chair of the Labour women's caucus Sue Moroney talks to Lisa Owen.
