Theories regarding the elusive earl, who would now be 76, have been numerous and far-fetched over the 38 years he has been missing and he has been reportedly spotted in countries like South Africa, Australia and Ireland. When Mr Bingham was asked if he thought his brother had escaped to Africa, he said: 'I'm sure he did, yes. But what connection there is I don't know'.
But Mr Bingham moved to South Africa to escape the media glare after his brother vanished and now lives in Johannesburg. Speaking to the Daily Mirror, he said he didn't want to speculate on where his brother is or was and whether he was dead or alive. Mr Bingham, who apparently bears a striking resemblance to Lucan, said the last contact he had with him was before the murder. Many police officers involved in the case believe he fled the country with the help of his wealthy friends. Others have suggested he committed suicide but no body has ever been found.
However, Lord Lucan's wife Lady Veronica Lucan, believes her husband died the day after the murder by jumping off a ferry. The 72-year-old widow, who lives as a virtual recluse at her home in London, rubbished claims he fled to Africa saying 'it does not make sense'.
She said he was 'not the sort of Englishman to cope abroad', adding that he couldn't speak foreign languages and 'preferred English food.'
The revelations follow a BBC report on Inside Out this week where a former personal assistant to Lucan’s friend, casino-owner and zoo-keeper John Aspinall, claimed that not only was the peer living in Africa in the early Eighties, but he also saw his children on at least two occasions. The woman, named in the programme as Jill Findlay, says she arranged travel tickets for Lucan’s eldest two children to travel to Kenya and then to Gabon, where ‘their father would observe them... just to see how they were growing up’.
However, Mr Bingham said he had no knowledge of that and admitted he has 'never really been in touch with them'. He said he is often asked to speak about the case but chooses not to.
Lucan had three children with Lady Lucan, Frances, George and Camilla. Lady Lucan, who lost custody of the children in 1982 following a breakdown, said it was 'ridiculous' to suggest the children went abroad and said she would have known if they had.
She also questioned why the woman claims only Frances and George went abroad and not Camilla. She said her husband would have wanted to see all three children, whom she is no longer in touch with. Meanwhile, this week an antiques dealer came across what he claims must be Lucan's watch which is believed to have come from South Africa.
Cedrick Lincoln, 58, believes the watch with a chunky black strap which he bought last week from another dealer for £5,000 could hold vital clues as to what happened to Lucan. The other dealer claims that it was discovered in a South African township. Inscribed on the underside of the watch is the message: 'Presented to Lord "Lucky' Lucan" The Old Fossil' by his friends at the Clermont Club Mayfair December 1967'.
After some digging, Mr Lincoln found photographs of the aristocrat wearing a similar watch. The discovery supports claims that the fugitive fled to South Africa, where some believe he is still living.
IS LORD LUCAN STILL OUT THERE?
The British aristocrat was famously smuggled out of the country following the death of Sandra Rivett - the family's nanny - in 1974. Lucan, born Richard John Bingham in 1934, was officially declared dead by the High Court in 1999. He started gambling early in life and learned how to play poker during his national service years.
In 1955, he got a job with a small merchant bank, William Brandts, for £500 a year. However, he retired in 1960 having won £26,000 over two nights playing 'chemin de fer' at a gambling party run by John Aspinall. But he would eventually accrue huge debts, before disappearing following Ms Rivett's death.
Every few years, Lord Lucan is 'spotted' again - sometimes in Australia, sometimes in Africa, sometimes in the UK.
THE FATAL EVENTS OF THURSDAY, NOVEMBER 7 1974
At 9.45pm, Lady Lucan, in great distress, burst into the Plumber’s Arms, the pub near her home in the exclusive area of Belgravia in central London. With blood streaming from several wounds on her head, she cried: ‘Help me, help me, help me! He’s in the house! He’s murdered my nanny!’
Lady Lucan, who was estranged from her husband, said he had killed their nanny and tried to kill her. Police found the couple’s three children asleep in their beds, unharmed, and when they went to the basement they were greeted by a macabre scene.
The basement lightbulb had been removed, but in the semi-darkness, officers made out a pool of blood with a man’s footprint in it (a bloodied towel was in a bathroom), a blood-stained length of lead piping and a mailbag containing a body.
The body was that of Sandra Rivett, the children’s live-in-nanny, who was the same height and build as Lady Lucan. According to Lady Lucan — living apart from her husband and in a bitter custody dispute over their children — she’d gone into the house to look for the nanny, but was attacked by her husband, whom she recognised by his voice, before managing to flee. When she returned with police, Lucan was gone. After the attack, he went to the home of friends, telling them he had found the nanny had been murdered. He left his friends at 1.15am.
Three days later his car was found abandoned in Newhaven, East Sussex, with bloodstains on the front seat and a length of lead piping matching the one found in the Belgravia basement. There was speculation that he had committed suicide, but no body was found. And there were rumours that his gambling friends John Aspinall and billionaire Jimmy Goldsmith had helped him flee the country.
Two years later, Aspinall gave an interview in which he said that if Lucan had sought his help he would have given it unconditionally. By then, the inquest into Sandra Rivett’s death had been held and Lucan was named as her murderer. The missing peer was declared legally dead in 1999.
