As Prince Harry and his wife-to-be prepare for their wedding, what will life have in store for the newlyweds?

Overseas tours

Meghan Markle has already expressed a desire to 'hit the ground running' as a full-time royal.

The couple will head to Australia in October for the Invictus Games competition for wounded servicemen and women, which Harry founded.

They are expected to jet-set round the world on official tours, with a trip to the US, where Ms Markle was born on the cards.

Commonwealth

Harry and Ms Markle will also play a significant role in matters relating to the Commonwealth family of nations.

The prince has been appointed a Commonwealth Youth Ambassador by the Queen, and is president of new youth charity the Queen's Commonwealth Trust.

He said Ms Markle is 'hugely excited' to be joining him in his Commonwealth work.

The Queen is head of the Commonwealth, but, as she no longer carries out foreign travel, the task of travelling to Commonwealth countries falls to the younger generation.

With Ms Markle's work with the UN and Harry's love of Africa and his successful Caribbean tours, the couple are seen as ideally placed to support the monarch's Commonwealth duties.

Charities

Ms Markle will begin to pick the charities she wants to work with.

Charity patronages are long-term commitments and Ms Markle is expected to choose some connected with subjects she feels strongly about such as women's issues and worldwide humanitarian causes.

A new home

Harry and Ms Markle will set up home in the prince's current apartment, Nottingham Cottage, in the grounds of Kensington Palace.

But the newlyweds might also find themselves the new owners of a country residence, with properties rumoured in Norfolk and Herefordshire.

Children

Harry, a doting uncle to the Cambridge children, has admitted he would love to have children, and, in an interview in 2016, Ms Markle said becoming a mother was on her 'bucket list'.

'I can't wait to start a family, but in due time,' she said.

Security

As an HRH, Ms Markle will be entitled to round-the-clock security, with her own personal protection officer paid for by the taxpayer.

Harry has grown accustomed to the intrusion since childhood, but Ms Markle will have to adjust to a lifetime of being guarded by the Metropolitan Police's Protection Command.

Royal life

If she chooses to, Ms Markle can be waited on hand and foot with valets, dressers, hairdressers, chefs and butlers at the ready.

The Queen will lend her priceless tiaras, and couturiers will rush to be given the chance to design her gowns.

As a celebrity she is already accustomed to a privileged way of life.
