A City banker accused of trying kill her magistrate mother by lacing Diet Coke with poison will stand trial on September 22.

Kuntal Patel, 37, denied attempting to murder Meena Patel, 54, with Abrin, a naturally occurring toxic substance when she appeared at Southwark Crown Court today.

Patel, who worked for Barclays Bank in Canary Wharf, was arrested earlier this year after officers swooped at the £450,000 home she shares with her mother and chemist sister Poonan.

It followed raids by counter terrorism police at three properties across the capital.

Wearing a black jumper and glasses, Patel, of Park Road, Stratford spoke only to confirm her name. She denies attempted murder on December 18 2013 and acquiring a biological agent or toxin on December 11 2013. She faces a trial on September 22 at Soutwark Crown Court.
