Britain’s highest-profile private landlord, Fergus Wilson, is understood to be putting all of his properties on the sales market today.

The portfolio, in and around Ashford, Kent, is thought to consist of 300 homes.

It is known that Wilson has been giving notice to some tenants.

They include one who asked Wilson to write to Kent Police after the tenant’s application for a firearms and shotgun licence, and the need for a gun cabinet in the rental property.

An indignant Wilson wrote to the police, sharing his letter with media, saying that his own licences had not been renewed.

In his letter he said: “Kent Police has taken the view that I am not a person who should hold a firearm/shotgun licence.

“Consequently it is totally inappropriate that Kent Police should ask me to give my permission relating to firearms and shotguns.

“[Tenant’s name] is an ideal tenant with no arrears of rent. He has a young baby of about one year. I have given him a Section 21 notice to end his tenancy as I am selling the house.”

We have asked Wilson, who has long threatened to get rid of his entire portfolio, to clarify how many properties he is putting on the market.
