Mr Reilly said the issue is “close to their royal highnesses’ hearts”.
Prince Harry, 34, and Meghan, 37, touched down in Casablanca airport on Saturday evening, although flight delays meant they were two hours late for their welcoming ceremony.
The couple are staying with Morocco’s King Mohammed VI at a royal residence.
During their visit to Morocco – which will be an important market for the UK after Brexit – the pair will visit the famous Atlas Mountains and the country’s capital, Rabat.
They will see a girls’ education project, meet young social entrepreneurs and visit programmes working with children with disabilities and those with mental health problems.Last year, the royal couple took their first official tour as a married couple with a 16-day royal trip around Australia, New Zealand, Fiji and Tonga.
Meghan is heavily pregnant with the couple’s first child.
They announced the pregnancy in October last year. Meeting crowds in Merseyside in January, the duchess revealed that she does not know the sex of the baby and it is due at the end of April or start of May.
She reportedly travelled to New York earlier this month for her luxury baby shower with her friends, including some celebrities.
