What happens when the Prime Minister suddenly stops being Prime Minister?

One day you're the most powerful person in the country, the next you're irrelevant, forced into retirement 30 years ahead of schedule and find yourself asking 'What do I do now?'

Miles Jupp stars as Henry Tobin - Britain's shortest serving and least popular post war PM (he managed 8 months).

We join Henry soon after his crushing election loss. He’s determined to not let his disastrous defeat be the end of him. Instead Henry's going to get back to the top - he's just not sure how and in what field..

This week Christine encourages Henry to make the most of his green credentials.
