This is completely confusing. Is it support for her personally regarding an abusive ex? What kind of support? Mental health, counselling, security?
Security should be dealt with by Hoyle's office and the police surely not the Labour Party now she is an MP? If she is affected by stalking then she'd do better to run to the press explaining that the police are not taking enough action than blamng her party. If counselling mental health support then she is on a salary now most of us can only dream off and can pay for it herself.
As others have said OP, nothing to do with being a feminist forum, just baffled at your point? People who lose jobs, lose the job's benefits. There has to a mechanism for party discipline or there would be chaos and it would be like Teresa May's last weeks permanently in parliament. There has to be consequences for not being in the PLP and a half in / half out situation when domestic abuse support is not your employer's responsibility (except support for time off perhaps if necessary for health or court cases and that's a parliament thing not a PLP thing) just makes no sense. Why stop there with that support? What about child care, bereavement support, etc, etc.
I don't think what she can be losing can be that big a thing (the support, not the domestic abuse) because I don't understand what big level of support she might be getting that she could not get elsewhere - like the rest of us do. Or are you suggesting she has lost thousands of pounds on a personal security guard or something? Exactly what is it that you think has been taken away?
