Sir Keir Starmer mounted a diplomatic effort to prevent football's world governing body from shifting the England versus Mexico World Cup fixture six hours earlier than scheduled.
The Prime Minister directed government officials to argue against FIFA's proposed alteration, with full backing from the Football Association.
Downing Street became involved after the FA raised concerns about the potential schedule change, alerting Number 10 to the developing situation.
The Government's opposition centred on fears that an earlier start would disadvantage the Three Lions, as players would have significantly reduced time to acclimatise to the challenging conditions at Mexico City's Azteca Stadium, situated 2,240 metres above sea level.

| PAForeign Secretary Yvette Cooper also played a crucial role in the Government's response, reaching out directly to Britain's Ambassador in Mexico City.
Ms Cooper requested that diplomatic staff on the ground make formal representations opposing any last-minute alterations to the fixture schedule.
The Foreign Secretary's primary concern was safeguarding the approximately 3,000 England supporters who had travelled to Mexico for the tournament.
A sudden six-hour advancement of kick-off would have left many fans unable to reach the stadium in time, potentially causing thousands of British travellers to miss their team's crucial World Cup encounter entirely.
FIFA's consideration of moving the match stemmed from forecasts predicting severe thunderstorms, with officials expressing concern about lightning strikes and potential flooding around the iconic venue, which accommodates more than 87,000 spectators.

| GETTYHowever, the proposal met resistance from both nations' football governing bodies, who objected to such significant changes being made fewer than 48 hours before the scheduled kick-off.
Both associations cited disruption to supporters' travel arrangements and interference with squad preparations as grounds for their opposition.
Mexico's head coach Javier Aguirre was particularly forthright in his criticism, describing the proposed alteration as a "kick in the gut".
Following more than five hours of uncertainty, FIFA ultimately confirmed the fixture would proceed at its originally scheduled time, though adverse weather conditions on the night did push the actual start back by sixty minutes.
England emerged victorious with a thrilling 3-2 triumph, securing their passage to a quarter-final meeting with Norway in Miami this Saturday.
Speaking at a Downing Street reception on Monday, Sir Keir reflected on the behind-the-scenes efforts, stating: "We had to battle with the FA to get it back to where it was, which was counterintuitive."
