Kenya's exiled former anti-corruption investigator John Githongo says he wants to return to Kenya, more than a year after fleeing in fear of his life.
Mr Githongo still fears for his life
Mr Githongo has been living in Britain since he resigned from the government.
Threats to his safety arose after he revealed a massive corruption scandal involving several government ministers, known as the Anglo-Leasing affair.
He told the BBC he wants to carry on his work but is worried no prosecutions have been made over the $600m scam.
Kenyan Justice Minister Martha Karua has said that the affair remains under investigation.
Mr Githongo is still worried for his safety but told the BBC that, "it is only a matter of time" before he does return home.
Mrs Karua said Mr Githongo was welcome to come back.
President Kibaki is expected to seek re-election next year
"John is living in exile because he has chosen to," she said
In response, Mr Githongo agreed that, "Yes, exile is a choice that I have made," but said that the invite to return was a first.
Mr Githongo also spoke of his disappointment regarding the lack of prosecutions.
"I am concerned because it has been two-and-a-half years since we uncovered some of these things. It only became public six months ago but this is something we started trying to deal with when I was still in government as far back as April 2004."
When asked whether he regretted his actions, Mr Githongo said: "One always takes a personal choice - it is not an easy choice, it has implications that change one's life really for good.
"But mine is one life and what I did, I felt I had to do."
The Anglo-Leasing affair involved contracts worth hundreds of millions of dollars being awarded to fictitious firms for items such as hi-tech passports.
President Mwai Kibaki won 2002 elections on a pledge to tackle corruption which had plagued the previous administration.
