A banker accused of trying to kill her magistrate mother at their Stratford home by lacing her Diet Coke with a poison more deadly than ricin is to stand trial in July after appearing at Southwark Crown Court today where she was further remanded in custody.

Kuntal Patel,36, is alledged to have plotted to kill Meena Patel,54, using abrin-a rare poison extracted from the seeds of a Peruvian plant.

She was arrested by counter terrrorism officers at the £450,000 home they share in Park Road earlier this month after US homeland security is beleived to have tipped off Scotland Yard’s Counter Terrorism Command about a website based in the US which specialised in selling lethal toxins.

She is not facing terrorist charges, but is accused of attempted murder between December 10 2013 and January 26.

She will return to court fora plea and case management hearing on April 25.

She has yet to enter a plea.
