A Labour MP rents out flats with black mould and ant infestations, the BBC has discovered.

Jas Athwal, the newly-elected MP for Ilford South, owns 15 rental flats, making him the biggest landlord in the House of Commons.

In one block of seven flats owned by Mr Athwal nearly half the tenants said they had to regularly clean their bathroom ceilings to remove mould.

The BBC also saw evidence of ant infestations in a number of the seven properties.

“The ants are everywhere,” one resident said, pointing to insects climbing up a door frame. “They are on my kid’s body and on their clothes.”

Another resident said they had been threatened with eviction by the letting agent if they complained about problems in their flat or started claiming benefits.

Mr Athwal said the properties were managed by an agency, he had not been aware of these problems, and denied any tenant had been threatened with eviction.

He said he did not take on tenants on housing benefit to avoid conflicts of interest with his role as the local council leader.

He described himself as a “renters’ champion”.
