It’s understood that the focus of the trip will be on Commonwealth countries, so destinations could include Bangladesh, India, Malaysia and Singapore, according to Mail Online.
Sources told them they believe Kate and William could also visit Sri Lanka, where a terror attack on Easter Sunday left at least 258 people dead.
The sources added: “But less likelihood of a stop in Brunei, which has attracted criticism for its human rights record. It is believed China was considered but was ruled out.”
The duke and duchess previously visited Singapore and Malaysia during the Diamond Jubilee tour on behalf of the Queen in 2012. The couple also travelled to India on tour in April 2016.
According to Mail Online, the overseas trip will be weeks apart from a visit by the Duke and Duchess of Sussex to Africa.
It’s not clear whether the Duke and Duchess of Cambridge’s three children Prince George, Princess Charlotte and Prince Louis will be joining them on the tour.
Princess Charlotte, four, is set to start at Thomas’s Battersea school in September, which Prince George, five, currently attends.
They accompanied their parents on their trip to Canada in 2016 and Poland and Germany in 2017. Prince George undertook his first overseas visit to Australia in 2014, when he was just eight months old.
Kensington Palace declined to comment.
