James Graham's play employed a wonderful conceit: taking the audience back to Margaret Thatcher's childhood and her bedroom, where 12 year old Margaret enacts her future triumphs and disasters with the help of her collection of teddy bears and dolls.Margaret has been sent upstairs again. And she’s not to come down from her room above the grocer's shop in Grantham until she says sorry. But that’s all right. Because hidden in the toy chest is Teddy. And in the wardrobe is Jonathan. And under the bed is Cecil Parkinson. And so Margaret goes on a fantastical journey, transforming from the young Miss Roberts into the formidable Mrs Thatcher, in order to escape her past, reconcile her present, and prepare for her future. But will she be able to summon up the strength to apologise? And should she have to..?
