Max Spiers was found dead in an apartment in Poland in October 2016

An inquest into the mysterious death of a British conspiracy theorist who died after 'vomiting black liquid' on a trip to Poland has been postponed.

The sudden death of Max Spiers, 39, remains shrouded in suspicion after a friend discovered his body during a trip to Poland.

His inquest opened in December 2016 and the court heard he vomited two litres of black blood before he died.

It was due to resume this Thursday in Maidstone, Kent, but has now been adjourned again with no explanation for the delay and little prospect of it happening this year.

The father-of-two, from Canterbury, had become world-famous in the shadowy world of conspiracy theories and allegedly made many 'enemies' in his investigations.

Shortly before his death, Mr Spiers was said to have been probing the lives of well-known figures in politics, business and entertainment.

At the time his mother Vanessa Bates, 63, said she feared the worst.

She said: 'I think Max had been digging in some dark places and somebody wanted him dead.'

Authorities in Poland, where Mr Spiers was attending a conference, initially concluded the sudden death was due to natural causes.

Mr Spiers was known as a 'supersoldier' by his followers and those in the conspiracy and supernatural community, and went to school with the actor Orlando Bloom.

After his body was repatriated to the UK, doctors at a Margate hospital were unable to determine the cause of his death.

Kent Police then launched a joint investigation with Polish police into the conspiracy theorist's death.

At an inquest opening in Canterbury in December 2016, the court heard how the 39-year-old had been visiting Poland to speak at a conference after holidaying with a friend in Cyprus.

In a statement, coroner's investigations officer Caroline O'Donnell said: 'When they returned, Mr Spiers became ill with a high temperature and was weak.

'The following day, Mr Spiers vomited two litres of black fluid. The friend called a doctor who attempted resuscitation before pronouncing him dead.'

Max's mother (pictured with her son), is hopeful the investigation will shed light on his mysterious death

His mother is hopeful the investigation will shed light on the mysterious death.

'It's been a long time coming, but I'm just relieved that at last something is happening and there is a proper investigation and inquest,' she added.

Her theory was shared by many online, with other conspiracy theorists, UFO investigators and bloggers calling the circumstances of Mr Spiers' death suspicious.

At the time, Coroner Alan Blunsdon told the court he was still awaiting a report from Polish authorities, adding that the workload of Kent Police may delay forensic analysis of Mr Spiers' phone and computer.
