Rangers fans sang the national anthem ahead of their Champions League clash against Napoli at Ibrox.
The Scottish club are playing their first match since the death of Her Majesty Queen Elizabeth II.
Rangers, a club known to be pro-royalist, asked UEFA to play the national anthem after a minute’s silence in honor of the late Queen.
However, those requests were turned down, with UEFA saying the decision was made for consistency with them having already decided not to play the competition’s anthem as a mark of respect.
But Rangers still opted to play the national anthem through the Ibrox PA system, with fans duly joining.
The decision could result in a fine from European football’s governing body.
A mosaic of Her Majesty was displayed shortly before the two teams entered the field. Chants of Rule Britannia were also heard in the stands as the two groups of players stood in the tunnel.
A period of silence in memory of Elizabeth II was then impeccably observed before the national anthem was played.
