Giles Coren and Sue Perkins take their relationship to the next level as they prepare for their very own royal wedding. The pair assume the roles of a modern prince and his princess-to-be as they agonise over every step of the wedding planning process, from choosing the dress to arguing over the vows. In true Supersizers fashion the programme culminates with a lavish wedding banquet featuring dishes from past royal nuptials, including everything from sturgeon a la royale to the Queen Mother's favourite eggs drumkilbo.

Restaurant critic Giles Coren and writer and performer Sue Perkins spend the week on the diet of a wealthy Edwardian couple. Cooking for them at home is best selling cookery writer Sophie Grigson.
