A "Covid summer school fund" is being set up by the government to help feed children during the holidays, after a campaign by footballer Marcus Rashford.
Children eligible for free school meals in term time in England will get a six-week voucher, Downing Street said.
Prime Minister Boris Johnson welcomed Mr Rashford's "contribution to the debate around poverty".
The Manchester United forward, 22, had called for a U-turn in plans not to offer meals during the holidays.
