Nepal's Crown Prince Paras has been taken to hospital after suffering what doctors say is a mild heart attack.
He underwent an angioplasty operation in Kathmandu's Norvic hospital and is "much better", the hospital says.
Crown Prince Paras is a controversial and unpopular figure who has been at the centre of a number of scandals.
He is the only son of King Gyanendra. A constituent assembly due to be elected in November is to decide whether the monarchy should be abolished.
