A Muslim women's group has written to Labour leader Jeremy Corbyn claiming women have been stopped from becoming councillors by Muslim men in the party.

Muslim Women's Network UK demanded an inquiry into "systematic misogyny displayed by significant numbers of Muslim male local councillors".

"They don't like women to be heard, to be empowered," it told BBC Newsnight.

Labour said it had the best record of any of the parties in selecting female and ethnic minority candidates.

As Mr Corbyn prepared to speak to the Association of Labour Councillors on Saturday, BBC Newsnight spoke to about a dozen Muslim women up and down the country.

They appeared to point to a pattern of obstruction from within Labour Muslim ranks and back up Muslim Women's Network UK's complaints of sabotage.

Optician Fozia Parveen claims her efforts to become a Labour councillor in Birmingham in 2008 were scuppered by men within the party.

She said: "At the time, I was aware of a smear campaign against me.

"They said that I was having an affair with one of the existing councillors.

"I was quite taken aback. People were turning up at my family home trying to intimidate my mum."

Ms Parveen said Muslim men told her mother to stop her from pursuing becoming a councillor.

She added: "It would be members of the local Labour Party. I didn't see them myself but my mum did say it was them."

Shazia Bashir was the first choice for Labour in a seat in Peterborough in 2007.

She claims that when her father said he would not support her, Muslim men from within the local Labour Party made her step aside. They deny the claim.

"Because I didn't have my father's consent and support, I had to step down. I was pressured into stepping down," said Ms Bashir, who was 31 and married with two children at the time.

Jean Khote, a sitting Labour councillor in Leicester, said good women candidates were barred by the membership in some areas with high Muslim populations - and that was kept from people higher up the party.

She said they would say there were not adequate candidates among the women, which she said was not true.

"There were brilliant women on the panel. I've met them and had discussions with them," she added.

Newsnight was told similar stories by other women who wished to remain anonymous.

One said: "They spread this slander about me... It's the way they get to you."

Another said she had been told by Labour members "Islam and feminism aren't compatible".

An advocate for gay rights was told: "This is un-Islamic. Leave that for white people." And many spoke of being criticised for being too Westernised.
