The Duke of Cambridge is set to return to a homeless organisation he last visited with his mother as the charity reveals the refurbishment of one of its centres.
On Friday William will tour the refurbished St Vincent's Centre in London, which is run by the charity, The Passage.
Established in 1980, the charity helps homeless people transform their lives by providing resources designed to encourage, inspire and challenge.
The organisation runs the UK's largest support centre for homeless and insecurely housed people - and since its inception has helped over 100,000 individuals.
William last visited The Passage as a child with his brother Prince Harry and mother Diana, Princess of Wales, in 1994.
After looking around the new facilities, which include a new restaurant, winter garden and training space, he will meet members of the centre.
The Duke will then attend a short reception and unveil a plaque to mark the official opening of the revamped centre.
William is an avid supporter of schemes and organisations that support the homeless - much like his late mother.
In 2009 he spent a night on the streets of London to raise awareness of the issue in an event organised by Centrepoint - another homeless charity of which he is patron.
