Episode 6 explores the first days, weeks and months of a new government. We speak to those who've entered No.10 alongside the prime minister on day one, found themselves suddenly running a government department, or have welcomed a brand new political team into office as a senior civil servant, including: Ed Balls, Jonathan Powell, Gus O'Donnell, Harriet Harman, Polly Mackenzie and Nick Macpherson.

What actually happens on a prime minister’s first day? How can a new government make the most of the first months in office? And what’s it like for civil servants, adjusting to having a whole new team of politicians in charge?
