A Clapham-based addiction centre has spoken of its delight after the Duchess of Cambridge announced she is to become patron of its charity.

Hope House provides 22 beds for second stage treatment for women is part of the Action on Addiction organisation - the only UK charity working across the addiction field in research, prevention, treatment, professional workforce development and support for families and children.

The duchess recently paid a private visit to Hope House in Rectory Grove and spoke at length to a number of clients about their addiction and personal journeys to recovery.

Nick Barton, chief executive of Action on Addiction, said, “It is a great honour for the Charity that Her Royal Highness has chosen to become our patron.

"Addiction is a consuming condition that results in a great deal of harm to individuals, families, communities and society as a whole."

The duchess' decision to volunteer her time to help the Scout movement has been welcomed by the South London Scouts which operate in Wandsworth, Greenwich, Southwark and Lewisham.

Paul O’Brien, head of the South London Scouts, said: "One of my big missions is to encourage people across South London who have the enthusiasm and ability to put something back into their communities. "That’s why we are so excited that the Duchess of Cambridge has chosen to help out in Cub Scout Packs and Beaver Scout Colonies."

The practice of members of the royal family supporting charities through formal patronages is thought to have been around for 300 years.

But recently many more charities have benefitted from the extra profile and fundraising potential that having a royal patron brings.

The Queen and the Prince of Wales have accepted more than 600 and 400 patronages respectively.

A spokeswoman for St James' Palace said: "The Duchess' research into charitable sectors drew her to see that addiction is at the heart of a number of social problems in the lives of vulnerable people and communities- particularly children who are also affected by addiction.

"Her patronage of the Scouts reflects her keen in interest in sports and hobbies. She is a former Brownie and competed in sports at school. she is very aware of the positive benefits outdoor activities can bring."
