There is an interesting story over at the BBC - Muslim women 'stopped from becoming Labour councillors'
In the article it states that Muslim Women's Network UK has written to Jeremy Corbyn demanding an enquiry.
The article also mentions some smear campaigns that have been used to discredit candidates.
As someone who is not involved in any political party so I can't really verify or comment on the types of claims mentioned and if it is normal business (with perhaps men also being trargetted with different types of smear campaigns?) but it is an interesting read.
