Alps murders: French police 'covering up', says brother
20 October 2013 Last updated at 12:35 BST
The brother of a British man killed along with his wife and mother-in-law while on holiday in the Alps in September 2012 has denied arranging their murder and described the accusations as 'ridiculous.'
Zaid-al-Hilli has accused the French police of "covering up" the real target of the killings and offered to take a lie-detector test.
He has never been charged and remains on bail after being arrested on suspicion of conspiracy to murder.
The French prosecutor said there was a very serious feud between the brothers, but this is denied by Zaid.
