Prince William has been booed by sections of the crowd at Wembley during the FA Cup final on Sunday (NZ time), sparking outrage among UK politicians and journalists.
Audible boos rang out around the Wembley Stadium as the Duke of Cambridge, who is president of the Football Association, was introduced and made his way across the pitch to shake hands with the Chelsea and Liverpool players before kick-off.
The boos then got louder as Prince William stood singing Abide With Me and then God Save the Queen - the British national anthem - as sections of fans gesticulated and made obscene hand gestures.
Liverpool fans have been booing the national anthem dating back to the 1980s.
It's reportedly because of the Conservative Government's 'managed decline' of the city, followed by the failings of the Government after the Hillsborough disaster, the Liverpool Echo reported.
Politicians around the UK have slammed fans for booing the Prince, with one calling it "shameful".
"I utterly condemn any fans who booed Prince William at Wembley today," Commons Speaker Sir Lindsay Hoyle said.
"The FA Cup final should be an occasion when we come together as a country. It should not be ruined by a minority of fans' totally shameful behaviour. In this year of all years - the Queen's Platinum Jubilee - this is dreadful."
Tory MP and former Culture Secretary Karen Bradley said: "It is utterly unacceptable and disgraceful that fans booed Prince William. I would urge the FA to take all necessary action and pursue those responsible."
Sir Ed Davey, leader of the Liberal Democrats, said: "We have the most wonderful Monarch and those fans who booed do not represent their clubs or our country."
Former BBC Royal Correspondent Michael Cole said the booing was "disgraceful and deplorable" and called for the Football Association to take action.
"There is no excuse for that sort of behaviour. I've been a football fan for 67 years, and I've never heard such a thing," he told The Mail on Sunday.
"We don't want sycophancy in this country, but we want respect. And respect is due to the head of state. Respect is due to the Queen, particularly at 96 when the whole world has been celebrating the fact that, after not being able to attend the State Opening of Parliament, she was at least able to go to the Royal Windsor Horse Show yesterday. So it's bad manners."
Cole also criticised the BBC football commentators for failing to mention the Liverpool fans' "repulsive behaviour".
Liverpool kept their hopes of completing a historic "quadruple" alive with a nervy and absorbing 6-5 penalty shootout victory over Chelsea after the showpiece somehow ended 0-0 after extra time.
