The son of the nanny murdered by Lord Lucan has spoken of his 14 year mission to get justice for his mum.
Neil Berriman's tenacious campaign for justice started in 2008 when he opened a fading envelope left to him by his adoptive mum after her death.
He almost threw it on a fire but decided to open it and inside he found documents which revealed that his birth mum was the nanny killed by Lucan - Sandra Rivett.
