The MP for Hove has asked the Royal Mail why Portslade residents have to include Brighton as part of their address.
Mike Weatherley said that he had been contacted about the issue by a number of Portslade residents since he was elected to the House of Commons last May.
Now he is campaigning for the requirement to include Brighton as part of the address to be dropped.
It is one of a number of local identity campaigns that Mr Weatherley is running.
Another is for better signs to be placed at the boundary points of both Hove and Portslade.
In a letter to Moya Greene, the chief executive of Royal Mail, Mr Weatherley has pointed out that the town of Portslade is not in Brighton and that it does not even share a boundary with Brighton.
It is separated from Brighton by the town of Hove – and residents of Hove are certainly not expected to include Brighton in their addresses.
Mr Weatherley said: “I find it entirely bizarre that Brighton must be included when Portslade is not in Brighton nor is it even joined to Brighton.
“Portslade has a sorting office so it is entirely right that it is recognised as a post town in its own right.”
I would like them to remove Brighton from Southwick addresses in their autonpostcode, their is an albert road in sourhick and Brighton so I’m never sure if we receive all our mail – and Southwick is west Sussex not East.
