Prince William, 36, is to make history later today by being the first official royal visit to Israel.
He will be visiting the country along with Jordan and the Occupied Palestinian Territories later today during a five-day tour of the Middle East.
It is the first visit by a British royal family member and he will be meeting both Israeli Prime Minister Benjamin Netanyahu and Palestinian Authority President Mahmoud Abbas.
He will also visit Jerusalem’s Old City, as well as the grave of his great-grandmother, Princess Alice of Greece.
His wife, Kate Middleton, 36, will not be joining Prince William for an understandable reason.
The Duchess of Cambridge is currently on maternity leave following the birth of her third son, Prince Louis.
While the royal often travelled on tour while pregnant, it is thought that she has chosen to stay behind with her family.
Kate will also be looking after her other children Prince George, 4, and Princess Charlotte, 3.
She has only made recent appearances to Prince Harry and Meghan Markle’s wedding, and the Trooping of the Colour.
The wedding of Harry and Meghan was considered a family event so was not seen as an official engagement.
Her maternity leave is expected to last six months, as per royal tradition.
While this means Kate may not be seen again before October, she previously stepped out just a few months after giving birth to Prince George in 2013.
Royal biographer Duncan Larcombe told Harpers Bazaar Online that it was “traditional” for royal family members to take six months away from the public eye after giving birth.
With Prince Louis being just two months old, it makes sense for Kate to want to remain at home with him before returning to the limelight.
The Duke of Cambridge will return to the UK after five days in the Middle East, and the pressure on him will be high due to the challenging nature of the visit.
The complex political situation will mean Prince William will need to tread carefully, with the Foreign Office previously advising against royals to travel there.
Prince Charles previously travelled to the region for a state funeral in 2016, but even the Queen has not travelled there herself.
It isn’t the only way Prince William has broken with tradition while travelling as a royal family member.
He also flies on the same plane as his children, the heirs to the throne.
An unofficial rule has previously advised against doing so in the case of an accident that could affect the lineage to the throne.
