Prince Harry and Meghan Markle's battle over security whilst in the UK continues this week as it is revealed they will have to use their own bodyguards during a trip to Manchester on Monday.
The couple reportedly landed on UK soil yesterday morning after flying commercial, and did not appear to have their children with them in their first return to the country since the Queen's Platinum Jubilee in June.
But tensions remain over Prince Harry's legal battle with the Home Office over its refusal to provide a heavy police protection to the Sussexes - despite them offering to pay for it.
Now the couple face relying on their own security staff and event organisers to keep them safe at a One Young World event they will attend in Manchester tomorrow, the Sun reports.
One Young World is an organisation which promotes young leaders and brings together communities from across the world, supporting young campaigners and representatives with impactful projects.
Meghan has been supporting the organisation, which has previously seen speakers such as Emma Watson attend, for several years.
She is expected to deliver the keynote speech at the opening of the four-day conference on Monday.
A spokesperson for Greater Manchester Police confirmed to MailOnline that the couple's security is being 'privately secured'.
Prince Harry has been embroiled in a lengthy legal battle with the UK Home Office after it previously refused to provide police protection for the couple to return to the country after they stepped back from royal duties and moved to California.
The Duke of Sussex, 37, has been taking legal action against the department after being told he would no longer be given the 'same degree' of personal protective security when visiting from the US.
His representatives have previously told of how he wants to bring wife Meghan Markle and their children Archie and Lilibet to visit from the US, but that they are 'unable to return to his home' because it is too dangerous.
Although the whole family did make the trip for the Queen's Platinum Jubilee, the couple stayed out of the limelight. Their children, Archie and Lillibet, are believed to have remained at home in California this week.
After stepping back from royal duties, it was decided that the prince should be taken off the list for the Protection of Royalty and Public Figures (Ravec), whose members receive automatic security funded by the taxpayer.
In July, Harry won the right to bring a High Court challenge against the Home Office over his security arrangements in the UK.
A High Court judge said Harry had an 'arguable' case on four of the five grounds on which he brought his claim, and that his lawyers will be able to make his arguments at a judicial review of the Home Office decision.
After his official role ended and he became 'a privately funded member of the Royal Family with permission to earn his own income and pursue his own charitable interests', Ravec withdrew guaranteed police support.
