The inquest into the death of a 17-year-old girl at Dreamland will be held over four days with a number of witnesses giving evidence.

Emily Stokes died after attending the Margate theme park’s Worried About Henry gig in the summer.

She is believed to have taken MDMA, and after becoming ill at the event, she was taken to QEQM Hospital, where she suffered a cardiac arrest and could not be revived.

She was one of 22 teenagers - aged between 15 and 18 - taken to hospital after falling ill during the drum ‘n’ bass festival on June 29.

Today a pre-inquest review was held at Oakwood House in Maidstone. Coroner Patricia Harding set a date of April 7 for the full inquest to take place over four days, when she will hear evidence from various witnesses and legal representatives.

The ‘interested persons’ called forward at today’s pre-inquest review include Sands Heritage - which owns Dreamland - and the security and medical teams.

Waltham Forest Council will also give evidence, as Emily was a “looked after” child and the authority acts as a “corporate parent”.

The coroner explained to each party what was expected of them at the full hearing and asked them to answer specific questions.

Ms Hepburn said: “Emily was a young lady who was having some changes in her life.

“She had recently moved back into London from Kent and was trying to forge her own path and was perhaps doing so in a way a corporate parent would not approve of.

“The question is how much can the corporate parent do about that.”

Questions were also asked of the legal representative for Sands Heritage, Alexandra Tampakopoulos.

The coroner asked how much information about the event would be released to the public.

Ms Tampakopoulos said: “The evidence contains matters relating to security measures.

“We’re concerned that if some of that information was released it would make way for bad actors, criminals and terrorists.”

It was agreed that Sands Heritage and the coroner would come to an agreement on what evidence would be released.

In July, Dreamland released a statement as part of the review into its licence.

Bosses said the park was not to blame for Emily’s death, instead pointing the finger at the “scourge of illegal drugs on society”.

They further revealed that CCTV showed Emily removing a bag of what appeared to be drugs concealed in her bra swallowing a pill and handing some to two of her friends.

However, the coroner said there were discrepancies on whether Emily took drugs before or during the Dreamland event. No further details on this were given.

The East Kent Hospitals Foundation Trust, which runs the QEQM, and the Kent Central Ambulance Service were also present.

A second pre-inquest review was arranged to be held on March 6.

At the full inquest, witnesses who were at the festival and had contact with Emily before her death will also give evidence.

On July 24, district councillors let Dreamland keep its licence at a review, instead of imposing extra conditions.

These included a more stringent drug policy and checks, no under-18s at high-risk events and further training for staff, including on age verification.

All 22 hospitalised teens are understood to have been suffering the effects of drug intoxication, with one being put into an induced coma.

The coroner said what happened to them will be relevant in Emily’s inquest.

Kent Police declared a major incident on the day but allowed the gig to finish to avoid a “large-scale public order” disturbance.

The event attracted more than 7,000 people - with 342 of them under 18.
