perhaps he doesnt reply to your letter becuase he knows that your only purpose in writing is to attack him. You're a labour party activist not a worried constituent. You know it. He knows it. Perhaps he has better things to do - like working for his constituents. I assume he is sending so many written questions in order to demonstrate how his constituents are being let down in all sorts of ways. And come off it, if you rely on buses then you'll want somebody to highlight their failure to run.
