Chris Mason: Why it was always likely Sue Gray would go

Tellingly, one element of the rejig is the government’s list of planned announcements, known internally as “the grid”, that had been under the command of Ms Gray.

It will now be under the control of the No10 communications team, where some believe it should always have been.

“Look at that news grid, week after week after week of stories about freebies,” one senior figure said to me the other day with an exasperated tone.

They were articulating a double frustration – a frustration at the initial failure of judgement in accepting the donations and how they were spent, and a frustration at how long it had taken the party to deal with the row.

Other Labour figures, though, are privately jittery that all this “looks like the leakers have won”, as one put it to me.

Labour made much of saying they would offer an alternative to the chaos of recent Conservative administrations.

And yet within weeks there was backbiting and infighting.

The prime minister will hope this marks the end of it.
