Murder charges

Port allegedly met the men on gay websites and invited them to his house, where he is said to have poisoned them with the party drug GHB and dumped their bodies in or near a churchyard in east London.

The murder charges relate to these four deaths over 14 months:

Port, who appeared in court via video-link from Belmarsh Prison, also faces four alternative charges of manslaughter for each of the murder counts, which he also denies.

He spoke only to confirm his name and enter pleas during the brief hearing.

He is due to stand trial on October 4, which is expected to last up to 10 weeks.

Police did not initially link the deaths, but after further investigation they were referred to the Metropolitan Police homicide and major crime command on October 14 last year.

The force has referred its handling of the case to the Independent Police Complaints Commission.
