British Prime Minister Boris Johnson was facing pressure Tuesday to make a policy U-turn as opponents and allies alike rallied behind a young soccer star’s campaign to help families struggling with food poverty. Marcus Rashford, who plays for Manchester United and England’s national team, wants the government to provide free meals for needy students over the summer holidays. Rashford, 22, wrote an open letter to all of Britain’s lawmakers on Sunday, describing how, as one of five children of a hard-working single mother, “we relied on breakfast clubs, free school meals, and the kind actions of neighbors and coaches.”
