A ten-point plan for Rishi Sunak

2. You should resign. 

3. This need not be the end of your career. You can show what it means to accept responsibility by doing the right thing. 

4. You do not need to call on Boris Johnson to go. You say that is a matter for him. You say you will support the government from the backbenches. 

5. You know deep down that Johnson is toast. But you can recover and rebuild if you separate yourself from him now. 

6. If you stick with him, you sink together. 

7. If he survives the next few weeks he is going to sack you.

8. Even to people like me (they know I loathe the guy and consider him to be the worst prime minister of all time), his people make clear his contempt for you.

9. People can recover from principled resignations.

10. Do the right thing and you will feel better. Over and out.
