A handful of football supporters booed England players as they took the knee before the team’s opening Euro 2020 game at Wembley.
The jeers were, however, drowned out by clapping and cheering from other parts of the 22,500 strong crowd.
The catcalls came despite the Football Association (FA) urging people to respect the anti-racism stance.
England’s opponents Croatia did not “take the knee” before the kick-off.
The FA asked fans to support players taking the knee.
In a statement the football authority said:
“As the team has reiterated many times, they will collectively take the knee ahead of their fixtures during the tournament.
“They are doing this as a mechanism of peacefully protesting against discrimination, injustice and inequality.
“This is personally important to the players and the values the team collectively represents.
“We encourage those that oppose this action to reflect on the message you are sending to the players you are supporting.
“Please respect their wishes and remember that we should all be united in the fight to tackle discrimination. Together.
“They will do their best for you.
“Please do your best for them.”
England won the game 1-0 with a goal from Raheem Sterling.
England’s next game is expected to be a raucous affair against Scotland – “the old enemy” – in Glasgow on Friday.
