London (Web Desk): Pakistan Tehreek-e-Insaf (PTI) chairman Imran Khan’s ex-wife Jemima Goldsmith and her brother clashed publicly in a bitter row on Twitter over London Bridge attack .

Zac Goldsmith’s siblings exchanged angry tweets after wealthy financier Ben Goldsmith linked the atrocity to mass immigration.

Mr Goldsmith , 36, said British people were “starting to understand what life is like in Israel, under the constant threat of attack”.

He invoked Enoch Powell’s famous “Rivers of blood” speech from 1968 and asked: “How much blood constitutes a river? And when might we acknowledge that perhaps Enoch Powell had a point on the dangers of mass migration.”

The siblings are the children of the late billionaire financier Sir James Goldsmith , who was also the father of unsuccessful London mayoral candidate Zac Goldsmith .

Seven people died and dozens more were injured by terrorists who mowed down pedestrians on London Bridge and launched a knife attack in Borough Market.
