British Prime Minister Theresa May has condemned FIFA over what she called an "utterly outrageous" ban on international players wearing poppies.
England and Scotland meet at Wembley on Nov. 11, Armistice Day, and there had been hopes that players would be able to wear commemorative shirts to honour those who have given their lives in conflict.
But FIFA turned down the request because its regulations say teams may not display political, religious or commercial symbols on their kits.
Speaking at Prime Minister's Questions, May hit out at world football's governing body and told MPs: "I think the stance that has been taken by FIFA is utterly outrageous.
"Our football players want to recognise and respect those who have given their lives for our safety and security. I think it is absolutely right that they should be able to do so."
She said it was a matter for the English and Scottish Football Associations, but that there was a "clear message" from the House of Commons that "we want our players to be able to wear those poppies."
The Prime Minister added: "Before they start telling us what to do, they jolly well ought to sort their own house out."
Football Association chairman Greg Clarke told ITV: "My personal opinion, and actually the same opinion I hold as the chair of the FA, is that of course we should wear poppies.
"We're commemorating millions of people who gave their lives in wars over the last 100 years and they deserve that, and the people who lost relatives deserve that, and that's our plan.
"We're negotiating in good faith with FIFA to try and find a solution, but there will be poppies at Wembley."
A FIFA spokesperson told Press Association Sport: "FIFA fully respects the significance of commemorating Remembrance Day.
"The laws of the game are overseen by the International Football Association Board and applicable to all 211 member associations. The relevant law 4, para. 4, clearly states that the players equipment should not carry any political, religious or commercial messages.
"The laws are applied uniformly in the event of similar requests by any member association to commemorate similar historical events.''
On Tuesday, it had been reported that FIFA looked set to allow players from England, Scotland and Wales to wear poppies on armbands during next week's World Cup qualifiers.
Such a decision would have repeated a precedent set in 2011 and Press Association Sport reported that all parties were keen to find a sensible solution.
England wore armbands with poppies on them when they played Spain on Nov. 12, 2011. Scotland also did so in Cyprus, as did Wales when they hosted Norway.
