Ayan Hassan can't stop smiling. The Somali-born mother of three is talking about appearing in a short film to promote the London catering co-operative she helped to set up a year ago. Hassan, 30, is proud of her achievements since arriving alone in the UK as a refugee 11 years ago. Having left her mother and siblings in Kenya after the family fled civil war in Somalia, she is now an active member of her north-west London community.

The catering project – Spice Caravan – has grown from a group of six refugee mums cooking at school events, to a business with a £30,000 annual turnover, supplying festivals, private parties and the local farmers' market.

None of this would have been possible, says Hassan, without the support of Salusbury World, a small charity based at her children's school, Salusbury primary, in Brent. The country's only refugee centre within a school, the charity helps children and families adjust to school and community life in the UK. As well as providing start-up funding of £500 and kitchen space, Salusbury World helped Spice Caravan to access external training in skills such as business planning, finance and food hygiene.

Glenda Jackson (Hampstead and Kilburn) (Lab): While thanking the right hon. Lady for switching on the green light, I note that she referred in her statement to “a package of measures to reinforce confidence in properties above tunnels”. That issue affects many of my constituents. When and to whom should my constituents make representations to have their concerns calmed?

Justine Greening: I will be writing today to all the people affected directly by HS2, and that will include making sure that people in areas that will have tunnels underneath them will receive all the details they need to understand how this process will work.
