Boris Johnson told young entrepreneurs today he once ran his own business selling ceramic tiles, with help from his artist mother.

He was launching a new initiative called the Hatch, which helps young people set up their own businesses in The Brick Box cafe in Tooting Market.

The Brick Box opened an internet cafe this week and will be run by young people aged 18-25 who want to gain work experience.

Tooting businesses will mentor and give advice to the participants.

The space will also be used by refugee charity Klevis Kola Foundation, which will be running study sessions and homework clubs in the space.

Team London is funding the project and youngsters can also bid for £500 grants to help kick start their projects.

Mr Johnson said his own business may have been more successful if he had been given advice.

He said: "It did not last very long, we didn't have the benefit of advice or a mentor, but it might have been successful if it did.

"These young people have so many great ideas, we want to plant the seed and allow it to germinate.

"London’s professionals from any field and any size of business can play a part, giving up as much or as little of their time as they can."

The Brick Box founder and social entrepreneur Eleanor Barrett said: "We are looking forward to hatching the creative ideas that these partnerships will create and seeing young people go forward into their futures with the increased confidence and resources they need to succeed."

Annabel Datiari, 22, of Wandsworth who plans to get involved said she would like to become the next Levi Roots selling peanut curry.

She said: "The Brick Box will give me the support and confidence I need to do it, and to move forward with my ideas."
