Sir Vince Cable, MP for Twickenham and the leader of the Liberal Democrats, joined Blue Peter gardener Chris Collins in building a wildlife garden.

Today's at St. Stephen’s Primary School in Twickenham is part of two days of go green initiatives in the borough organised by energy supplier, Octopus Energy.

The school has converted their disused sandpit into a ‘bug hotel’, bog garden and bird feeder, also planting trees and flowers to support natural flora and fauna.

Sir Vince Cable said: “Air pollution is a problem for us all. It’s great to see businesses like Octopus Energy getting involved in planting trees and gardens in schools to teach young people the importance of the environment and the air we breathe.

“I’m thrilled to help the pupils of St. Stephen’s to recycle their old sandpit and turn it into a delightful wildlife garden.”

Tomorrow Octopus Electric Vehicles will take over Richmond Athletic Grounds to kick start its UK-wide summer tour and showcase a selection of electric car models, including Tesla, BMW, Nissan and Renault.

There are also activities for the kids to take part in, with a fun-filled day of face painting, a bouncy castle and a colouring station to enjoy. The event runs from 10am to 5pm.

In the run up to the eco-days, Councillor Seamus Joyce, shadow spokesperson for transport, street scene and air quality for Richmond said: “During a week in which we celebrated World Environment Day, we are delighted Richmond has been selected by Octopus to launch their fantastic range of electric cars.”
