The FA Cup final will kick off no later than 4.45pm after the Metropolitan Police deemed the Manchester derby at Wembley to be a high-risk fixture.
It is understood no decision has yet been taken regarding the kick-off time for the match on June 3 – between Manchester City and neighbours Manchester United – but the police will not sanction a 5.30pm start time.
United’s penalty shoot-out victory over Brighton set up the first Manchester derby in a cup final in the competition’s 151-year history.
ITV was preparing to screen the match and the Epsom Derby on the same afternoon.
The horse race had been due to start at 4.30pm but neither the Jockey Club nor ITV has yet confirmed whether the police advice regarding the cup final would affect their scheduling.
