Tooba Yahya is to be expelled from Canada for the murder of her three daughters, Zainab (19), Sahar (17) and Geeti (13).

But only after she has served 25 years in jail, without parole. She was sentenced to that term alongside Mohammad Shafia and their son Hamed.

The killings, plus that of Rona Amir Mohammad, 52, Mohammad Shafia’s childless first wife in a polygamous marriage, are believed to have been committed because the women refused to obey the “rules” laid down for them.

They have all been behind bars since first arrested in July 2009. Apparently they killed them by pre-drowning them and then pushing a family vehicle into a canal.
