Sometimes you've just got to feel sorry for people who are famous or always facing cameras and TV cameras - don't you. A picture of the PM was spotted by a cheeky journalist who noticed that the Prime Minister David Cameron appeared to have begun to back comb his hair from half way across the top of his head. Now I would not claim to be an expert in politics but I do know a thing or two about hair and my advice to him would be along the following lines ....' David, don't forget to pack a small hair brush - and remember One Direction is not just the name of a pop group it's also a good rule of thumb for the management of hair on top of a gentleman's head. In your case I'd suggest you brush across and to the right and perhaps give it a bit of a scruffle when you're done. Don't forget if it can work for Boris it could work for you..... now run along.'
