That would be the same Liz Truss that said "I am backing Remain as I believe it is in Britain's economic interests" ? Sometimes trying to understand Johnson's motives is like being inside someone's head after they have had a bad hallucinogenic trip.
She has risen through the ranks without a trace and she is even being touted as a successor to Johnson. I am bemused but will give her a chance to make something of her new additional remit before I have an opinion on how good she is.
