The Conservative MP Paul Holmes, who represents Eastleigh, has announced that he is resigning as a parliamentary private secretary in response to the revelations in the Sue Gray report.

Holmes, who was elected in 2019, was PPS to Priti Patel, the home secretary. A PPS – an unpaid ministerial “bag carrier” – is not a member of the government, but is considered part of the “payroll vote” and obliged to support the government in all divisions. Being a PPS is normally a stepping stone towards becoming a minister.

Revelations from the Sue Gray report that staff and cleaners were not treated properly is both disappointing and unacceptable. It is right that the prime minister apologised to staff. It clearly showed a culture in No 10 that was distasteful, and I am glad that there have been several reforms that Sue Gray has welcomed.

It is clear to me that a deep mistrust in both the government and the Conservative party has been created by these events, something that pains me personally as someone who always tries to represent Eastleigh and its people with integrity. Whether that is taking up your issues in parliament or helping people with their problems closer to home, since 2019 we have completed over 12,000 pieces of constituency casework. It is distressing to me that this work on your behalf has been tarnished by the toxic culture that seemed to have permeated No 10.

I’m not going to pretend that this is going to fix everything for everybody immediately. There are still going to be pressures. But it’s a very, very substantial commitment by the government to getting us through what will be, I’m afraid, still a bumpy time with the increase in energy prices around the world.
