Meghan Markle and Prince Harry have been accused of carrying out "rogue royal tours" at a "pivotal time" by a royal expert.
The Sussexes have recently returned home to California after a four day excursion of Colombia - their second tour this year, after visiting Nigeria in May.
Royal biographer, Emily Andrews has suggested that the couple have only signed up to the "rogue royal tours" to "highlight themselves".
Andrews raised questions about why they have been carrying our the tours as the visits are not on behalf of the UK Government, the working royal family, or a charity - aside from their own non-profit Archewell Foundation.

"With Harry celebrating his 40th birthday next month and ongoing courtroom battles in the UK, it does feel like a pivotal time for the Sussexes in their attempts to ‘look forwards'."
It has also been claimed that the tours come at a time when the couple’s reputation has "taken a hit" in the US.
Andrews added that given the number of upcoming projects the Duke and Duchess are promoting, the timing of their "faux-royal tour" it notable.
