For those asking how Truss was chosen ahead of Sunak - Go and google who the ERG are. These are the (very far-right) people that hold all the power within the Tory party.
One time Chair was Rees-Mogg, now the detestable Mark Francois. They pressured Cameron to allow the referendum and wanted Brexit, they ousted May, backed Boris until they realised he was a liability and then backed Truss. There was no way they were going to allow Sunak to become leader.
The whole party has driven the country off the edge of the cliff and yet still no one talks about the biggest elephant in the room. Brexit has wrecked us, the pandemic and Putin made it all a lot more difficult to get through. Worrying times.
