Brenda Emmanus explores the art collection of Charles I, much of which is being reunited for a unique exhibition for the first time since his execution. Brenda hears the stories behind the works of art and learns how the collection was sold off by Parliament following Charles's death.

With exclusive access to the Tate's 'secret stores', where some of the new work will come from, members of its congregation explain how they feel the £260m transformation of this cathedral to contemporary art is money well spent, while others think its expansion in a time of recession is sacrilegious. Andrew Marr and Brenda Emmanus present from the opening night celebrations with contributions from Tate supremo Sir Nicholas Serota, artists Tracey Emin and Antony Gormley, critics Waldemar Januszczak and Jennifer Higgie, and comedians and painters Harry Hill and Vic Reeves.
