Celebrities and politicians from across the spectrum have come out in support of Marcus Rashford’s campaign to end child hunger in England, a day after the government voted against extending free school meals to disadvantaged children during the holidays. Representatives from the worlds of sport, entertainment and politics tweeted praise for the Manchester United striker. Gary Lineker ignored BBC impartiality guidelines to say: “Yesterday they voted against helping to feed our hungriest children during a pandemic. Never thought I’d tweet that.” In reference to the footballer’s last-minute goal against Paris Saint-Germain this week, he added: “Keep going @MarcusRashford and another late winner could be yours.” The flood of social media support for Rashford’s campaign came as a Conservative MP who defied her party to support Labour’s vote for free school meals during school holidays resigned from her government post. Caroline Ansell, the MP for Eastbourne and Willingdon, was one of five Tories who backed Labour’s motion on Wednesday to extend financial support for the poorest families through half-term and Christmas holidays amid the coronavirus pandemic. She stepped down as a parliamentary aide in the Department for Environment, Food and Rural Affairs, saying: “In these unprecedented times, I am very concerned to be doing all we can to help lower-income families and their children who are really struggling due to the impact of the virus.” She added: “I do not consider this extension could be in any way a long-term solution to this need, which is complex. There are better ways to help children, including linking meals to activities so they can also benefit from extracurricular learning and experience. “However, as we are still very much living in the shadow of the pandemic, vouchers are a lever – not perfect, not sustainable – but one which I thought could be used to reach families in Eastbourne and across the country in the immediate time ahead. I could not in all conscience ignore that belief.” Other celebrities backing Rashford included Hannah Cockroft, a five-time Paralympic champion, who signed and retweeted the England striker’s petition calling for an end to child poverty. The Sky sports presenter Kelly Cates, responding to Tory comments in the debate, tweeted: “Giving kids free meals makes them dependent on the state? What, like Marcus Rashford?” Among the tweets from politicians, the former UKIP leader Nigel Farage wrote: “If the government can subsidise Eat Out to Help Out, not being seen to give poor kids lunch in the school holidays looks mean and is wrong.” As well as backing the wider campaign, Lineker paid tribute to Rashford, tweeting: “Love this kid. He shouldn’t, of course, have to do this, but what a hero for doing so, and with such modesty and dignity.” There was also support from the Brookside and Holby City actor Nicola Stephenson, who posted the front page of the Mirror with the headline “So cruel” and tweeted: “Shame on all of them. @MarcusRashford, you are a hero.” The actor Robert Lindsay added his voice, writing: “Amidst all the current madness they actually arranged to have a vote????? A VOTE!!! for #FreeSchoolMeals ... and they voted against?” Labour’s opposition day motion was defeated on Wednesday evening by 322 votes to 261. The Conservative chair of the education select committee, Robert Halfon, had also backed the motion, which was aimed at forcing the government into taking action and followed months of campaigning by Rashford. Ministers argue that the situation is different from that during the nationwide lockdown and the summer holidays, when families entitled to free school meals received food vouchers. Opposing the motion during an ill-tempered debate in the Commons, the education secretary, Gavin Williamson, suggested that the best way to support children was through the welfare system. “There are real challenges around youngsters and tackling poverty, and Conservative members are intent on ensuring that we put in place actions to deal with those issues, and that families, children and individuals get the support they need. The best way to do that is through the welfare system; the best way to do that is by supporting people into work, as that is always the best route out of poverty.” However, the author of the government-commissioned national food strategy, the Leon restaurateur Henry Dimbleby, told the Guardian that free school meal support was the best way to make a positive impact on the diets of disadvantaged children. “However you feel in terms of ideology, that’s true, and you can’t let ideology get in the way of that.” Rashford’s campaign endorses the three main recommendations of Dimbleby’s plan, published in July: to extend free school meals to 1.4 million more UK children; to increase the value of Healthy Start fresh fruit and vegetable vouchers for pregnant women on low incomes; and to expand charity-led holiday hunger schemes. In response to the defeat of Labour’s motion, Rashford, 22, who was awarded an MBE in the Queen’s birthday honours list this month in recognition of his campaigning, told his 3.5 million Twitter followers: “Put aside all the noise, the digs, the party politics, and let’s focus on the reality. A significant number of children are going to bed tonight not only hungry but feeling like they do not matter because of comments that have been made today.”
