Slain Pakistani leader Benazir Bhutto's niece Fatima Bhutto has accused her aunt's party of carrying out massive rigging in some polling stations of Larkana in Sindh province.

Fatima, the daughter of late Mir Murtaza Bhutto – brother of Benazir, forced the closure of voting for around two hours at a polling station in Larkana over the alleged rigging by Pakistan People's Party (PPP).

Waving the voters' list, Fatima claimed that most of the names did not have their national identity card numbers on the list and this was nothing but "plain rigging".

The Sindh province is the stronghold of PPP, which is expected to sweep the polls.

Fatima claimed the PPP was trying to ride on a wave of sympathy following the killing of Benazir and was not following election rules.
