Most of the present cabinet weren\'t born when the Queen became monarch. So there\'s very little she hasn\'t seen, very little she doesn\'t understand. And anyone who doesn\'t listen to her view and consult her when necessary is missing a huge opportunity.\" Advertisement Sir John Major: \"Prince Charles will become king\" Events planned to take place during the summer to mark the Diamond Jubilee include the Queen leading a flotilla of a thousand boats along the Thames and a chain of beacons lit across the country.
