Campaigning schoolchildren will pay the education minister a visit next week to try to secure more funding for Lambeth primary schools.

More than 200 pupils from Immanuel and St Andrew Primary School will hand deliver postcards to MP Michael Gove on Tuesday carrying warnings from parents about the growing demand for primary school places in the borough.

The school’s headteacher, James Robinson, said: “We cannot go on like this, our schools are at bursting point.

“There is more pressure than ever before for us to provide more children with a primary school place.”

The school, in Buckleigh Road, Streatham, held a competition among students to create the postcard design and the winning entry, created by eight-year-old Malachi Vidal Martin, was sent to parents so they could write messages about their concern over school places.

Demand for reception and primary school places in Lambeth has risen by 40 per cent in just four years in some areas and the council has warned it would not be able to guarantee a primary school place for every child in the borough by 2015.

Most schools have been forced to take on bulge classes, a short-term solution that provides a school with 30 additional temporary places.

Immanuel and St Andrew Primary School has taken on a bulge class for the past three years to meet growing demand.

The school now needs to permanently expand, as do many others in the borough.

Julian’s Primary School, in Leigham Court Road, has already had to expand to a new site in Norwood due to an increasing number of applicants.

Lambeth Council cabinet member for children and young people’s services, Councillor Peter Robbins, said: “The reality is we need a fairer slice of Government funding to provide a proper long-term solution so children in Lambeth don’t receive a second-class education.”
