Lee Carsley remained silent as England players belted out "God Save the King" before Saturday's Nations League match against the Republic of Ireland
Jacob Rees-Mogg has said Lee Carsley needs to “zone out of his Irish Republicanism” if he wants to lead the national squad.
Speaking on GB News he said: “Sinn Fein MPs cannot take their seats in Parliament because they will not take an oath to the Crown.
“They do not accept the legitimacy of the constitutional settlement.
“Wanting to change it by democratic means is perfectly reasonable, and free speech must, of course, be upheld.
“The same principle applies to England football managers. They must support the nation whose team they seek to lead, even if they themselves are foreign.
“Singing the national anthem is a symbol of this, and if they will not accept the symbol, they should not hold the post.
“This applies to Lee Carsley, who needs to zone out of his Irish Republicanism and learn to sing God save the King.
“Otherwise, no one will believe he cares about the England team he wishes to lead."
