Prince Harry and Meghan Markle could be set to fill the shoes of the Duke and Duchess of Cambridge at the Commonwealth Heads of Government Meeting (CHGM).

The week-long event, due to be attended by William and Kate, takes place in April, which will coincide with the time that the Duchess of Cambridge is due to give birth to her third child, reports the Daily Mail.

New Zealand Prime Minister Jacinda Ardern, who is also pregnant, will be one of more than 50 heads of state flying in for what is expected to be the largest summit in the event's 25-year history.

With Brexit edging ever closer, it's thought that the presence of the royals will help ease the UK into better trade talks with non-Brexit countries.

Meghan, 36, now has a string of royal engagements under her belt and this could prove the last major event before the couple wed on the May 19 in Windsor.

The couple are already expected to attend the Commonwealth Day service on March 12.

The grand event, which includes formal dinners galore, is also a chance for the former Suits star to fully immerse herself in the Commonwealth, which remains a key talking point for the British monarchy.

The CHGM was originally scheduled to take place in the South Pacific Ocean island of Vanuatu but cyclone pam saw it relocated to UK shores.

Already in attendance are the Queen and Prince Charles, who will host several events during the week.

The Prime Minister has already expressed how vital the conference could be for the UK's relations with the rest of the world.

Theresa May said: 'As we look to create a truly global Britain, the deep partnerships that we share through a 21st century Commonwealth can help us strengthen the prosperity and security of our own citizens, and those of our many friends and allies across the world.'
