A minute’s silence will be held before the FA Cup final at Wembley and the Premiership final at Twickenham on Saturday in memory of the victims of the Manchester terror attack, with spectators at both showpiece occasions asked to arrive early in order to clear heightened security measures.

The Football Association and the Rugby Football Union have issued statements confirming remembrance plans for the 22 people who died and those injured in Monday’s bombing at the Manchester Arena, while also outlining the steps they are taking to ensure the safety of those attending their respective events.

It comes as organisers of the Great Manchester Run confirmed Sunday’s 10km event will take place despite the devastation caused by Monday’s blast and Uefa announced that next week’s Champions League final between Juventus and Real Madrid at the Millennium Stadium in Cardiff will be played under a closed roof for safety and security reasons.

“All supporters attending the upcoming matches at Wembley Stadium – the FA Cup final as well as the League Two and Championship play-off finals – are advised to arrive as early as possible to avoid queues and to support commemorations of the tragic events in Manchester,” read an FA statement. “Fans can be assured that all appropriate security measures are in place for the upcoming matches, which includes thorough searches upon entrance to Wembley. We strongly advise that all supporters arrive no later than one hour prior to kick-off and we encourage spectators to not bring any bags or unnecessary items with them.

“In addition to tributes being paid at Saturday’s FA Cup final, [which include commemorative wreaths being laid by the Duke of Cambridge and the FA chairman, Greg Clarke] all four teams and match officials taking part in the play-off finals on Sunday and Monday will wear black armbands and observe a period of silence prior to kick-off.”

An RFU statement read: “Fans can be assured that the safety of anyone visiting Twickenham Stadium is a huge priority for us. We have been operating enhanced security measures for some time and these will continue for all matches this weekend. All supporters attending the Premiership final on Saturday, or the Old Mutual Wealth Cup or any of the County Championship finals on Sunday, are advised to allow extra time to access the stadium and avoid bringing bags where possible.”

There will also be heightened security at Bramall Lane on Saturday evening before Kell Brook’s world title fight against Errol Spence Jr, with spectators told “no bags of any sort, including handbags, will be permitted”.

More than 35,000 runners attended last year’s Great Manchester Run, and with a higher number expected this year given there will also be a half-marathon it was expected the event would be postponed or cancelled following the government’s decision to raise the national terror threat level to critical. It goes ahead, however.

“Manchester is a truly resilient city and we look forward to successfully hosting these great sporting events,” said the city councillor Luthfur Rahman.

About 170,000 people are expected to be in Cardiff for the Champions League final next Saturday. Two days earlier the Millennium Stadium, which is to be rebranded the National Stadium of Wales for the contest, will also host the Women’s Champions League final, between Lyon and Paris Saint-Germain. The venue’s roof will be closed for that match, too.
