A schoolboy who wrote a letter to cheer up Marcus Rashford has now said Boris Johnson is not doing enough to tackle racism. On an appearance on Good Morning Britain, Dexter Rosier read out the letter to the Prime Minister urging him to do more to prevent these cases. “I Dexter Rosier do not think you are doing enough about racial abuse.
