Michael Portillo has said that Party Chairman Caroline Spelman should quit.  The former Defence Secretary made his intervention after it was revealed that Mrs Spelman’s former secretary, Sally Hammond, revealed that she was "shocked" at how much Tina Haynes, the nanny, was being paid a decade ago.

A ConservativeHome poll of 955 members (published last Thursday) found that most members thought Mrs Spelman should stand down while her case was being investigated by the Parliamentary Commissioner for Standards and that Eric Pickles should succeed her.

We stand by our view that Mrs Spelman will be exonerated and that she should not step down.  To do so would only encourage vexatious complaints against MPs and other public figures.  That hasn’t stopped speculation throughout this week that (post-Henley) she may resign.  An announcement could be made as early as today.
