My hon. Friend is clearly campaigning very hard on behalf of his constituents. Some years ago, I used to live quite close to his constituency, so I am well aware of the importance of those commuter rail services
to the people whom he represents. I suggest that his message to Govia should be to encourage it, yes, to put the need to provide for passengers first, but also to work more closely with its cleaning contractors and the transport police to ensure that trains are cleaned of offensive graffiti in a timely fashion and that the people responsible for the graffiti are identified and brought to justice.
