The mystery deepens after the body is found in a pond at Kensington Palace

The identity of a body found in an ornamental lake at Kensington Palace is unknown, bringing relief to a desperate family and deepening the mystery for British police.

The Daily Mail reports that the body was recovered from the pond at the palace, home to the Duke and Duchess of Cambridge, last weekend and identified as artist Endellion Lycett Green, granddaughter of former British poet laureate Sir John Betjeman.

Endellion, 51, had been missing for a week and the Metropolitan Police had made public appeals to help locate her.

But the discovery was revealed as a case of mistaken identity when Endellion appeared alive.

“My sister Endellion is alive and well,” her brother John Lycett Green told friends in a message quoted by the Mail.

“Sorry for all of you who, like us, were mourning the wonder that Delli is. They told us that a body was found and that it was her. It was not like that, and Delli was found last night,” the message continued.

“RIP the soul that was found at Kensington Round Pond on Saturday morning”.

A Scotland Yard spokesman told the Mail: “The death is being treated as inexplicable at this time, but is not believed to be suspicious. Investigations are ongoing.”

The palace has housed members of the British royal family since the 17th century and has been home to some of its most famous members.

It was the home of Prince Charles and Princess Diana and remained the official residence of the princess after their divorce.

The 16-foot-deep lake where the woman’s body was found was created by George II in 1730 and is home to the UK’s oldest model yacht club – the Model Yacht Sailing Association, which was established in 1876.
