"This vital research by the Sutton Trust has highlighted once more unnecessary inequality in our education system. It is not acceptable for disadvantaged children to fall behind because their parents cannot afford private tuition. In school education should not require supplementary tuition for pupils whose parents can pay when most cannot. Inequality in private tuition is one factor in the challenge to close the attainment gap. But this means we need to focus even more on high-quality education in schools.
"The Government must look to improve the quality of state schools to remove the need for private tuition. We should look to free schools where pupils on free school meals perform better than in any other type of school.
"The Government should commit to opening more free schools, targeted in the most deprived areas, allowing communities to implement new innovative ideas for closing the attainment gap."
