Dave,
I have made my point so there is little point in making it again.

But you have not made the point Dave. Stating it is not making it.

If it is an issue for all parties, why are there no complaints about it from those other parties as there are from Labour?
Why has the leadership and so many prominent members acknowledged that it is a serious problem for the party?

Unless you can answer that, you have no case.

If as you claim, Labour is working to address the issue, why are so many prominent people, all in a position to know, adamant that nothing has been done?

If you can only witter on about trains and flowers but not answer those basic questions, you have not made your point at all!
Are you going to?
