Meghan Markle to make keynote speech days after revealing interview

Before stepping down as senior members of the Royal family, the former Suits actress noted that Harry and herself were “upsetting the dynamic of the hierarchy just by existing".

The couple is reported to have arrived in the UK on Saturday but a spokesperson for the pair has declined to confirm their arrival.

On Monday, the couple will attend the One Young World summit where they will meet a group of summit delegates.

The Duchess, who is a counsellor for the organisation, will also give the keynote address at the opening ceremony.

The trip falls in the same week that a new Prime Minister is confirmed and is asked to form a government by the Queen.

The formal occasion will take place in Her Majesty's private summer home, Balmoral, in the Scottish Highlands.

This is the first time a Prime Minister appointment has been held here during her reign, prompting concern over the monarch's health.

It is not known whether Harry and Meghan will visit the Queen in Balmoral during their trip.

Following the UK trip, the couple will head to Germany for the Invictus Games Dusseldorf 2023 One Year To Go event which is taking place on Tuesday.

They are expected to return to the UK for the WellChild Awards in London where Harry will deliver a speech on Thursday.
