BBC News' Peter Gould reports

Her body was found 10 years ago and at first it was thought she had been killed by an animal, but it was later established she had been murdered.

Her father, John, has waged a long campaign to track down her killer.

A senior warden at the game reserve will appear in court in Nairobi on Monday.

Simon Ole Makallah will appear in court on Monday

Kenyan Attorney-General Amos Wako said the suspect, Simon Ole Makallah, was a senior warden at the Masai Mara game reserve where Ms Ward's body was found.

Mr Wako said there was sufficient circumstantial evidence to link Mr Makallah to the murder and did not rule out the possibility of more charges being brought against others, dependent on further forensic tests.

Attorney-General Amos Wako: "glad" that charges are now possible

"I am glad that after almost 10 years since the murder of Julie Ward, it is now possible to charge someone," he said.

Julie Ward, aged 28, died in the Masai Mara game reserve in Kenya nearly 10 years ago, yet no one has been convicted for her killing.

Mr Ward, who has spent an estimated £500,000 on his campaign for justice, thanked the investigation team: "(The Attorney General) has handled it with great understanding and, by allowing me to become part of the investigation, has wiped away all that was on the slate before."

John Ward's campaign has cost him around £500,000

The latest inquiry was independent of the government and the Kenyan police, whose role in the investigation was widely criticised.

The Kenyan government initially refused to search for her when she first went missing.

But her father, a millionaire hotelier from Suffolk, started his own search. and found charred parts of her dismembered body on a fire.

The authorities claimed she had been eaten by wild animals, but later two game wardens were charged with murder.

They were cleared because of lack of evidence at their trial six years ago.

Julie Ward's death harmed Kenya's image

The image of the African country as a tourist destination has also been harmed by this and other incidents.

In February of this year, a former Scotland Yard detective, Roy Chivers was killed in a private game reserve while on holiday in Kenya.

At the launch of the latest inquiry into the Ward case, Kenyan Attorney General Amos Wako promised that it would be comprehensive.

He said: "The team will investigate the new leads and all matters surrounding the murder of Julie with a view to obtaining sufficient evidence to mount a successful prosecution."
