Nadine Dorries frustrates Sunak by failing to officially resign as MP

Delay in formal resignation of Boris Johnson ally leaves prime minister facing byelection bind

Nadine Dorries has still not formally resigned as an MP, frustrating Rishi Sunak’s attempts to start preparing to replace her.

It has been five days since the former cabinet minister announced her intention to “immediately” step down. Boris Johnson and Nigel Adams, who announced their intentions to immediately quit hours after Dorries, have both officially resigned.
