Dr Mahathir Mohamad was interviewed by BBC World’s Mishal Hussein in London where the 83-year-old former premier was grilled on his legacy. The following is an abstract of the five-minute interview.

Mishal Hussein: One of Mr Badawi's fiercest critics was his predecessor, Mahathir Mohamad who was in power for 22 years. Dr Mahathir is here in London for a conference on the Palestinians and he is with me now in the studio.

Welcome to the programme. I wonder first if I can ask what went wrong as far as Mr Badawi is concerned because this is a man that you groomed to take over from you but then you didn't like what you saw.

Mahathir: Well, he did all the things that were wrong. In the first place, he brought in his family and involved them not only in party business but also government business. His main advisors are members of his family and the group of young people appointed by his son-in-law.
