There remains criticism of Sir Keir's time in the Shadow Cabinet when others more honourably refused to serve.
But Sir Keir can do no more now than implement the serious and swift measures needed to deal with what he rightly calls a stain on Labour.
In that context, his next move should be to remove its feckless general secretary Jennie Formby — along with her acolytes. And the retention of Andy McDonald in the Shadow Cabinet jars.
The coronavirus crisis has plainly upended politics and demands much of Sir Keir’s attention. But the need for him to return Labour to decency is no less pressing for that.
He has made a good start and appears to be sincere in his words. He has earned the right to be taken seriously.
