'Rebel' Prince Charles could put monarchy at risk, author says

Prince Charles, the "rebel" heir to the British throne, will face a battle to win over Britons and could even put the monarchy at risk if he does not temper his strong views when he eventually becomes king, a royal biographer says. Charles, who turns 70 next week, will be the oldest monarch to be crowned when he finally succeeds his 92-year-old mother Queen Elizabeth II.
