Sir Keir, who was discharged from Durham Police last month, said he was always confident he had broken no rules but that it was a “big moment” when the decision was made to investigate him. Politics Hub: Sunak vs Truss could get ‘pretty nasty’ He said: “I really hated it, being subject to a criminal investigation when you were the director of public prosecutions. “I hated it, I’m not like other people in a lot of ways who will say it’s okay, it meant a lot to me, it was a burden I carried. I tried not to show it physically, but it was there every day.” Image: Sir Keir Starmer investigated for video of him drinking beer with colleagues when social distancing rules were in place The Labor leader also said he knew “in his gut” he would have to stand down if found guilty but delayed committing to it because he wanted to discuss the decision with his wife. “A lot of people criticized me for taking two or three days to make a decision,” he said. “I put my whole career on the line and I wasn’t going to until I sat down like I did that Sunday and talked to Vic, my wife.” Sir Keir insisted he made the decision as “a matter of principle that those who make the rules cannot break them” and “not to somehow show that I was a goody two-shoes” – as some of his critics have suggested. He said his wife “supported him” through the decision, later calling it “fantastic”. The Labor leader has opened up about his family life, saying his biggest concern is the impact his work could have on his two children, who he is determined to keep out of the public eye.

He took issue with the suggestion he didn’t make it because people think he’s boring, telling Beth Rigby: “I don’t think I’m boring, I’m not going to pretend that politics is a brand of the entertainment business, running the country is a very serious matter and you need serious politicians to do it.” He was also told another voter concern is that people don’t know what he stands for – having championed a different vision for Labor under Jeremy Corbyn. But Sir Keir insisted that after the party’s disastrous performance at the last election, it needed to “think” about what went wrong and change.

However, he admitted he did not think it was appropriate for a prime minister to walk the picket line.
