The two suspects in the south London slavery case ran a Communist collective in the 1970s that worshipped the Chinese leader Chairman Mao, the Daily Telegraph has learned.
The husband and wife, who are from India and Tanzania originally, were arrested last week on suspicion of holding three women against their will for more than 30-years.
It is alleged they subjected them to beatings and emotional abuse and were only allowed to leave their Brixton flat in controlled circumstances.
The pair, who are both aged 69, arrived in Britain in the 1960s and were associated with a number of extreme left political groups known to the police and security services.
