Taylor Swift’s security presence has reportedly been stepped up to “presidential levels” ahead of her London shows.

The singer is due to perform five nights at Wembley Stadium in the British capital between Thursday and Tuesday.

It will be her first time back on stage since police in Austria last week foiled a plan to attack her concerts at the Ernst Happel Stadium in Vienna.

On Monday (British time), a report suggested the pop superstar’s security had been stepped up to levels usually reserved for US presidents.

A source told The Sun Swift had “presidential level” security around her.

“Taylor’s security and of those around her has always been paramount, but even more so now,” an insider told the paper.

“She and her dancers were told to ‘go to ground for their own safety’ in light of the Vienna threat. That’s why nothing has been said about the cancelled shows beyond the promoter’s statement.”

There will be increased security at the Wembley shows with The Sun reporting there was a dry run of the increased measures at the stadium for the Charity Shield football match on Saturday, while fans without tickets have also been asked not to gather outside the venue to listen to the gig.

Swift’s concerts in Vienna were cancelled after the threat was detected.

Three teenagers who authorities said had pledged loyalty to Islamic State were arrested over plans to carry out a suicide attack that would have caused a “bloodbath”.

One had chemicals, machetes and technical devices at his house, while another had got a job only days earlier with a company that did security for Swift’s Vienna venue.

“The main perpetrator has confessed that he was supposed to carry out a suicide attack with two accomplices,” Austrian Chancellor Karl Nehammer said.

“The suspects actually had very specific and detailed plans … to leave a bloodbath in their wake.”

In a statement, London’s Metropolitan Police assured fans there was nothing to indicate the Wembley shows will be targeted.

“There’s nothing to indicate that the matters being investigated by the Austrian authorities will have an impact on upcoming events here in London,” it said.

“[The city hosts] a significant number of very high-profile events each year, with millions of visitors having a safe and enjoyable experience.”

Officials said they would work closely with security teams and “other partners” to ensure there were appropriate safety measures for the much-anticipated gigs.

“As always, we will continue to keep any new information under careful review,” the Met said.
