After winning over the Shadow Health Minister, thoughts of becoming Prime Minister enter Ros Pritchard's head.

Ros's first few days in office are a whirlwind of meetings which leave her family feeling neglected.

Ros decides to sell off Westminster and set up parliament in Bradford. Georgina gets a boyfriend.

Twelve months has passed since Ros became Prime Minister. She is now a confident and slick leader who knows how to handle a crisis. That is, until a plane crashes over East London. Racial tension escalates as the country assumes it was a terrorist attack.

The country rebels against Ros when she introduces a one-day-a-week car ban. Emily moves back to No 10.

Will Ros keep her promise to never lie to the people, or cover up her husband's secret and keep her job?
