While last year delivered the shock of Brexit, there were other political shocks, such as Theresa May becoming the new Prime Minister.
This drama documentary looks at the battle between May and Boris Johnson. When David Cameron resigned, Johnson was the favourite to take the job, but in the end he never stood, partly because his key ally Michael Gove decided to stand in the election himself.
Mixing dramatised narrative with interviews with those behind the campaigns, this programme reveals how May became an unlikely Prime Minister – one who is now facing a new wave of pressure.
Theresa v Boris: How May Became PM is on BBC Two at 21.00.
