McDonalds is to launch a special World Cup burger that is said to be bigger than their Big Mac. Now get this the burger is supposed to be 40% larger than the Big Mac. The calories associated with this one are 669 and I'm not sure what the fat will be, but I'll make a guess of 40 to 50 grams. The new burgers will only be on sale for a six week period. This move has created some outrage from health campaigners and Liberal Democrat MP Steve Webb has actually ordered a petition against the burger because of the possible effect it will have on children's diets.
