A powerful parliamentary committee has accused the Home Office – both for this government and the last – of squandering billions of pounds on asylum accommodation and overseeing a “failed, chaotic and expensive” system.

He is now back in custody. Pippa Crerar and Eleni Courea discuss the ongoing firefighting at the Home Office and its impact on the public consciousness. Plus, what now for Labour after a crushing defeat in Caerphilly and the election of its new deputy leader, Lucy Powell?

To mark the anniversary, Patrick Greenfield took a tour of the site. He tells Madeleine Finlay about the journey a seed takes from arrival to cold storage, and how some are already helping to return endangered plant species to the wild.
