PKR president Dr Wan Azizah Wan Ismail has received a rare endorsement from her husband's arch nemesis, Dr Mahathir Mohamad.

The former prime minister said there is nothing wrong with women holding leadership positions, including that of menteri besar.

He said this when asked to comment on speculation that Wan Azizah, the wife of Opposition Leader Anwar Ibrahim, might replace Abdul Khalid Ibrahim as Selangor menteri besar.
