A mum of three who has become an Internet sensation through her fashionable fundraising campaign has launched a national volunteering crusade.

Caroline Jones, 47, of Harpenden, shot to social media fame after starting her ‘Knickers Model’s Own’ campaign, in which she wears charity shop clothing for every day of this year to raise money for Cancer Research UK (CRUK).

The campaign was launched at the beginning of the year in memory of Caroline’s mother, Mary Benson, and has since raised nearly £36,000 for the charity, meaning Caroline is 98 per cent of the way towards her £365,500 target.

After her mother’s death, Caroline also took on some of Mary’s volunteering shifts at Cancer Research UK in Harpenden.

She has now joined forces with DJ Trevor Nelson to launch BBC Radio 1 and 1Xtra’s #1MillionHours volunteering campaign.

The year-long appeal aims to get listeners to pledge one million hours of time to good causes and will shine a spotlight on all things volunteering.

Trevor said: “Caroline is an example of someone who has taken volunteering to the nth degree – she’s got the bug! She’s had a misfortune and turned it into something great that’s captured the nation’s heart.”

Caroline met up with the radio presenter last Tuesday (1) to kickstart the campaign at a Cancer Research UK charity shop in Marlyebone and was interviewed about the benefits of volunteering.

She commented: “I’ve got so much out of volunteering at the Cancer Research UK Harpenden shop and my mum absolutely loved it.”
