The founder of one of Pakistan’s biggest political parties has been arrested in London.
Self-exiled Altaf Hussain began the Muttahida Qaumi Movement (MQM) in 1984. He requested asylum in the 1990s and later gained UK citizenship.
The Metropolitan Police would only confirm that a man in his 60s had been held in an investigation into speeches related to the party.
Despite a split in the MQM, Hussain still wields considerable influence in the party and its main power base, Karachi.
