I like David Clelland, and although I don’t necessarily agree with his chosen phraseology in replying to an angry constituent, I can see why MPs occasionally lose patience with some of our less polite constituents. It’s almost always best simply to ignore the intemperate language and try to shame your correspondents with a polite and helpful response. Not always possible, unfortunately. A few years back I decided to throw someone out of my constituency surgery because he was being abusive. He clearly thought that, because I’m an MP, I have no choice but to sit there and take it. Wrong.
Reading a thread on one of Iain Dale’s posts recently, I noticed that someone had claimed to have asked the Parliamentary Ombudsman to “force” his own MP to respond to his numerous letters. You got that wrong, mate. The Parliamentary Ombudsman has no powers to instruct MPs to do anything. Neither should he; MPs are ultimately accountable to their constituents, not an unelected official.
