Instead, the couple - who quit royal life in 2020 - reportedly fear people will simply not turn up to see them.
Royal expert Duncan Larcombe told New Magazine: "The Sussexes are pragmatic, they're not stupid.
“I think their biggest fear won't be them being booed at by the crowds, it's them not having any crowds and being ignored - not drawing people to whatever they're doing publicly.
“That's what they'll be really frightened of, and it's entirely plausible too, if you take a look at the opinion polls."
Larcombe also said that he thinks Meghan will be nervous about her UK return, having not visited her husband’s home country since 2022.
He said: “They'll put on a brave face and won't let their fears show, but there's no doubt they'll be secretly anxious about how things are going to go.
“Meghan hasn't been here for a long time and, if anything, many people's feelings towards her have only grown stronger during that time, so it's bound to be a concern.
“But Meghan is very good at appearing calm and confident on the outside, regardless of how she might be feeling."
