France is looking likely to be the first country King Charles will make a state visit to as he embarks on his new role following the death of the Queen.
It is thought he may be paying a visit to President Emmanuel Macron as early as next month, which may be combined with a trip to Germany.
The European power is a surprising choice for a first visit, as monarchs normally make state visits to members of the Commonwealth.
The Foreign Office, which has the final say on where the royals will travel to, is said to be keen on the idea as it tries to build bridges with France following Brexit.
No state visits by the monarch have been conducted for the past seven years as Queen Elizabeth struggled to travel during the final years of her reign.
A visit to France would also enable the King and President Macron to work on plans for a major tree-planting scheme in Africa designed to tackle climate change.
While the King must now be apolitical, his passion for protecting the planet is well known and during a state visit it would be possible for Mr Macron to arrange an exhibition about the Great Green Wall project.
The ambitious scheme aims to plant a 30-mile-wide belt of trees across the African continent to halt the spread of the Sahara desert and replace lost forests, reported The Telegraph.
President Macron was one of many world leaders to attend the Queen’s funeral on Monday, along with his wife Brigitte.

“I think the British people and the King felt France’s deep affection for them and the emotion we shared.”
The first Commonwealth countries to receive a state visit are expected to be Australia and New Zealand next spring.
King Charles is currently staying at Windsor Castle observing a period of royal mourning, which will last for seven days after the funeral.
