The 22-year-old Manchester United and England football player caused a storm with his campaign to provide free school meals during the summer holidays to kids that needed them, and was made an MBE for his efforts.
But he recently gave Boris Johnson and his government a headache when he insisted it be extended to the Christmas holidays - the powers-that-be said no.
Instead, Marcus turned to people power, encouraging more than a million people to sign a petition asking for the Prime Minister to change his mind. While the sportsman was already a hero to many for his exploits on the field, he's now become a legend for his political activism.
"We are so proud of Marcus's tireless campaigning as a FareShare Ambassador and are in awe of the incredible support which Marcus has galvanised from the public." - FareShare CEO Lindsay Boswell
Marcus is also an ambassador for FareShare, the UK's largest charity fighting food waste and food poverty.
The charity's CEO Lindsay Boswell praised Marcus' efforts, telling HELLO!: "He may be a top-level footballer, but Marcus has never forgotten his humble beginnings – being raised in a single-parent family on free school meals.
"We are so proud of Marcus's tireless campaigning as a FareShare Ambassador and are in awe of the incredible support which Marcus has galvanised from the public. The FareShare staff and volunteers who met Marcus on his recent visit to our new warehouse in Manchester, all know just what a humble and unassuming young man he is."
