The trial of alleged serial killer Stephen Port is set to begin today.

41-year-old Stephen Port, of Barking, east London, was charged last year with the alleged murders of Anthony Walgate, Gabriel Kovari, Daniel Whitworth, and Jack Taylor.

Port allegedly used GHB to poison a number of victims, after meeting them on gay hook-up apps. The four bodies were found in and around the St Margaret’s Churchyard, Barking, between June 2014 and September 2015.

He is facing four counts of murder and administering a poison over the deaths, as well as an additional seven counts of rape, four of sexual assault, and six more counts of administering poison related to alleged attacks on other men.

Port previously pleaded not guilty to all the charges.

His trial is set to begin today at the Old Bailey, and is expected to last up to 10 weeks.

A separate investigation from the Independent Police Complaints Commission is ongoing.

The trial continues.
