MINISTER Mentor Lee Kuan Yew is well and intends to start travelling again, his son, Prime Minister Lee Hsien Loong, said on Tuesday in an interview with news agency Reuters.

'The years take their toll,' he said. 'He is well, he is frailer than before, he is 87 already, but his mind is still all there and he has been travelling, and I think he intends to travel again,' he added.

MM Lee suffered a fall in September and was admitted to hospital briefly later that week for treatment of a chest infection. His wife of 63 years, Madam Kwa Geok Choo, died last month, aged 89.

Reuters reported that many Singaporeans worry that MM Lee may not survive his wife for long and are concerned about what effect that could have on government and policy.

PM Lee said: 'Well, we will survive.

'The system has been established, the people have been put in place,' he said, adding that there have been two changes of prime minister since his father stepped aside in 1990.

MM well, to travel again
