The problems of mid-term PMs

Any Prime Minister who takes over mid-term has to contend with a certain set of problems. Liz Truss will wish she had been propelled through the front door of No. 10 by the momentum of a general election victory.

The first difficulty is that you have no personal mandate. This doesn’t just affect your relationship with the electorate, but your own MPs too. Boris Johnson benefitted from a sense that he was a winner, which made MPs more prepared to trust his judgment. Liz Truss will have to go that much further to persuade MPs of her political calculations. It also means MPs will be more jumpy if the polls are bad.

Next, you don’t have much time. Truss, rightly, emphasised the importance of delivery in her acceptance speech. But while a PM normally has four or five years to make good on their agenda, Truss will have just two before she has to go to the country.
