The Voice winner Jermain Jackman joined graduates from the government’s National Citizen Service (NCS) youth summer programme as they volunteered at the Groundwork community garden in Lower Clapton Road.

Jermain is a graduate of the scheme which has a volunteering component. He is also the youth advisor to the NCS, which has found a quarter of teens in London do not volunteer because they don't know how to get involved.

Jermain got stuck in helping move flowers left over from the Chelsea Flower Show into the garden, and clearing space for them to be planted, and said the experience reminded him of the importance of playing an active role in your community.

"We have a responsibility to empower people to get involved from a young age, especially as they are the leaders of tomorrow," he added. "One of the reasons I love NCS is that it shows young people just how easy it is to make a difference."

Places are still available for 16- to 17-year-olds to take part in the NCS programme this summer.
