The cynic in me sees the following trail of events in the Daily [s]Torygraph[/s] Telegraph.
1st Revelations about cabinet ministers. I see they’ve already had to concede that the Prime Minister’s cleaning payments were not a “scandal” after all but a legitimate expense.
2nd Revelations about Labour MPs plus a few scraps about Conservative MPs.
3rd Revelations about Sinn Fein plus maybe a few scraps about Conservative MPs to give an illusion of balance.
4th Revelations about Liberal Democrats, the Green Party, and everyone else who is not a Conservative supporter.
5th An apology but they feel that they are unable to pursue any further revelations about the claims of Conservative MPs due to the Police Investigation.
It is as well to remember that the Telegraph is owned by David and Frederick Barclay. A future Conservative Government might feel the desire to show their overwhelming gratitude in the time dishonoured way.
