Number 10 has said employers should consider allowing workers to come in late or take the day off on Monday if England win the Euros.
The confirmation came after Boris was asked about the chance of the day off during a visit to an energy company on Thursday when he said: “I think that would be tempting fate. Let’s see what happens.”
The Prime Minister has come under pressure to consider a one-off day off in the event of the Three Lions winning the tournament after defeating Denmark 2-1 at Wembley on Wednesday night.
More than 100,000 people have signed a petition calling for Monday to be a designated a bank holiday if England beat Italy in the final.
It reads: “Sunday 8pm is a difficult time for families to plan to be together for the event – knowing we have an additional day off the next day would significantly help this.
“Furthermore, a historic win should be celebrated. It would be expected for the winning team to parade the trophy, and a bank holiday would be a perfect time to do this.
“Also, English people would naturally want to continue to enjoy the win, giving the retail and leisure industry a much-needed opportunity to make up lost revenues.”
Downing Street has said it will set out any celebrations such as a victory parade for the England team “in due course”.
The Prime Minister’s official spokesman said: “I don’t want to pre-empt the outcome of Sunday’s match. Clearly we want England to go all the way and win the final, and then we will set out our plans in due course.
“We will hopefully, when England go on to win, then go on to set out our plans.”
