Authorities are assessing new information concerning private jet movements at Stansted Airport after fresh scrutiny linked to the activities of convicted sex offender Jeffrey Epstein.

Essex Police confirmed it is examining details related to private flights arriving at and departing from the airport in light of disclosures emerging from the recently published Epstein files.

The review follows calls from former UK Prime Minister Gordon Brown, who urged in the New Statesman that law enforcement should “urgently” revisit whether Epstein’s victims may have been trafficked into or out of the United Kingdom.

A previous investigation identified 87 flights connected to Epstein that either landed at or departed from UK airports between the early 1990s and 2018.

Stansted Airport has maintained that private aircraft operations are conducted independently, noting that it does not oversee passenger arrangements for privately chartered flights.

The police assessment is part of broader efforts to understand any potential connections between flight activity and trafficking concerns raised in the wake of the latest disclosures.

Civil rights leader Jesse Jackson has died at the age of 84, his family has announced, marking the passing of one of the most influential figures in the global struggle for justice and equality.

In a statement, the Jackson family said he “died peacefully on Tuesday morning, surrounded by his family”.

They described his life as one defined by service and purpose, noting that his “unwavering commitment to justice, equality, and human rights helped shape a global movement for freedom and dignity.”

The statement paid tribute to his decades-long activism, from his presidential campaigns in the 1980s to his efforts mobilising millions of voters and amplifying the voices of marginalised communities.

Jackson was the founder of the Rainbow PUSH Coalition, an organisation that became a central platform for advancing social and economic justice.

His family said he is survived by his wife Jacqueline and their children Santita, Jesse Jr., Jonathan, Yusef and Jacqueline, along with daughter Ashley Jackson and grandchildren. He was preceded in death by his mother Helen Burns Jackson, father Noah Louis Robinson and stepfather Charles Henry Jackson.

“Our father was a servant leader – not only to our family, but to the oppressed, the voiceless, and the overlooked around the world,” the family said, encouraging people to honour his legacy by continuing the fight for the values he championed.

Public observances are expected to be held in Chicago, with further details of memorial services to be announced by the Rainbow PUSH Coalition.

While the cause of death has not yet been confirmed, Jackson had faced ongoing health challenges in recent years. He was hospitalised in November and had been diagnosed with progressive supranuclear palsy, a rare degenerative condition.

In 2017, he revealed he had been diagnosed with Parkinson’s disease, which he described as a “physical challenge” even as he remained active in civil rights advocacy.

The United Kingdom and several European partners have pointed to new forensic findings as they renew efforts to seek clarity over the death of Russian opposition leader Alexei Navalny two years after he died in a Siberian penal colony.

Addressing delegates at the Munich Security Conference, UK Foreign Secretary Yvette Cooper said scientific analysis had detected epibatidine — a potent toxin associated with dart frogs — in samples taken from Navalny’s body.

She noted that the nature of the substance suggested it could only have been deployed by actors with significant capability, adding that the circumstances of Navalny’s imprisonment made the finding particularly concerning.

Moscow has dismissed the conclusions, with state outlet TASS describing the allegations as part of an “information campaign”.

However, a joint declaration from the UK, Sweden, France, Germany and the Netherlands emphasised that the toxin is not naturally present in Russia and is typically linked to certain wild amphibians found in South America.

On the sidelines of the conference, Cooper met Navalny’s widow, Yulia Navalnaya, as international partners reaffirmed their support for continued investigation.

The UK has also notified the Organisation for the Prohibition of Chemical Weapons regarding what it described as a potential violation of the Chemical Weapons Convention.

Prime Minister Keir Starmer praised Navalny’s determination and courage, saying his work continues to inspire efforts in defence of democratic values.

French Foreign Minister Jean-Noël Barrot also paid tribute, noting Navalny’s role in advocating for a more open political future.
