I will give it to Sunak, its a decisive way to deal with the "spineless" accusation. He's basically said none of his current MPs are up to the job.
I'm probably going to get crucified but I actually liked DC. Brexit was mad but he always seemed like he wanted to make the UK better so I was OK with him (although not austerity).
However when does it stop being a premiership and start being a dictatorship, if you can just appoint whoever you like into your government? Terrifying.
