Thae Yong Ho, Pyongyang's former deputy ambassador to London, defected to neighbouring South Korea last year and now claims the dictator's 'days are numbered'. He has since revealed he was lucky to have been able to bring both of his sons to London, unlike other North Korean diplomats who are forced to leave some of their children at home as 'hostages.' After his sons, now 20 and 27, learned about life in Britain, they began asking him questions such as why North Korea barred use of the internet and executed people without proper legal procedures, he said.< eod>
