It's the final week of MasterChef 2015. Over the past six weeks, the country's most promising amateur cooks have been whittled down to the best five. All of them have just one goal: to lift the coveted MasterChef Champion trophy. Tonight, the final five become the final four. The final five travel to Cambridge University's Churchill College, where they have the immense task of cooking a five-course dinner in honour of the man regarded as one of the greatest wartime leaders of the 20th century - Sir Winston Churchill. It is 50 years since he passed away, and historians, biographers and members of his family are gathering to remember him.
