Prince Harry's security is 'very much' dependant on the Home Office during his visit to the UK.
0Prince Harry's safety is heavily reliant on the Home Office, since he is denied his right to protection in the UK, it is thought.
The Met Police will provide 'rigorous' protection to the Duke of Sussex, who was denied a special security squad for his visit to his motherland.
"The UK government's protective security system is rigorous and proportionate," said a representative for the Home Office. "It is our long-standing policy not to provide detailed information on those arrangements."
Meanwhile, another insider told Express.co.uk that "Harry's team had to ensure that all the right security measures were in place before confirming his attendance at the event."
They went on to say: "Once those assurances were made by the Home Office, his attendance was confirmed and the go-ahead was given to make the announcement."
"Whenever Harry travels to the UK, his trips are always dependent on how secure he is," an insider told Express.co.uk earlier. "Before deciding whether to attend the Invictus Games anniversary event, his security team must be sure that St. Paul's is adequately protected."
