UK Prime Minister Keir Starmer backs calls for FIFA to investigate Argentina players who displayed a banner related to the Falklands Islands after their World Cup semi-final win over England. A Downing Street spokesperson says Starmer endorses a view expressed by Business Secretary Peter Kyle that FIFA should examine whether any competition or advertising rules were broken. The reports reference the banner shown by Argentina players and note Starmer’s position that the islands belong to the UK. The commentary also includes that the prime minister wishes both teams well ahead of the final, where Spain is involved, and that Starmer watched the semi-final while travelling to Ukraine by train for his overseas trip at the end of his premiership. In the accounts, FIFA is asked to determine whether the banner’s content breached applicable regulations. The available information does not specify what the banner said beyond relating to Argentina’s claim, nor does it detail any formal complaint, ruling, or disciplinary action by FIFA at the time of reporting.
