Sky reporting that Andrew MacKay has resigned as Cameron’s senior adviser over “unacceptable” expense claims.  Andrew MacKay was last seen having a run-in with the police over Damian Green.

UPDATE : MacKay is of course married to Julie Kirkbride MP.  So this could be double interesting…

UPDATE II : MacKay has just described the situation with his expense as an “anomaly” to Andrew Neil on the Daily Politics.  They are shameless.
