The chancellor, Jeremy Hunt, has been urged to use his spring budget to extend free school meals for all primary pupils.
The Scottish government has committed to providing free school meals for all primary schoolchildren, while in Wales the rollout of universal primary free school meals began in September.
But in England, only in London will all primary pupils get access to free hot meals for a year starting in September. All children in England can get free school meals until the end of year 2.
At least 55 MPs from various parties have signed the letter to Hunt, which was coordinated by the Labour backbencher Zarah Sultana, calling for every child to have access to a hot healthy meal each day.
