The MP for Harlow in Essex has called for the Government to end the inequality over the availability of free school meals to disadvantaged students.

Because of what the government has described as a "funding anomaly", Harlow College estimates around 350 of its students go hungry.
There are 103,000 college students across the UK eligible for free school meals but under the current rules can't apply. Of these, nearly 7,500 are from the East of England.
Student Josh McManus-Woods is eligible for free school meals, but because he attends Harlow college rather than a school sixth form he can't have the funding.
