Prince William revealed that his wife Kate Middleton is "immensely jealous" of his tour of Namibia, Tanzania, and Kenya and the reason behind the jealousy is one that most parents can relate to.

The Duke of Cambridge spoke about his engagements while at a British High Commissioner's reception in Windhoek on Wednesday and said, "I'm delighted to be visiting Namibia for the first time. I am only sorry that my wife Catherine is not able to join me. She is immensely jealous, particularly as I am looking forward to a few good uninterrupted nights' sleep this week, away from my wonderful children".

Ever since welcoming their third child Prince Louis in April, the Duchess of Cambridge has been on maternity leave although she did attend a few select family and friend affairs including Prince Harry and Meghan Markle's wedding in May.

Prince William started on his journey earlier this week and is due to return on Sunday. The 36-year-old Duke of Cambridge admitted that he was looking forward to a "few good uninterrupted nights' sleep" while on his work trip. 

As he was addressing guests on Tuesday night, he said that he was "delighted to be visiting Namibia for the first time," before adding, "I am only sorry that my wife Catherine is not able to join me". Kate Middleton, on the other hand, has stayed at home to look after the couple's three children- 5-year-old Prince George, 3-year-old Princess Charlotte, and 5-month-old Prince Louis.

Prince William has campaigned against the killing of elephants, rhinos, pangolins, and other species and also added that poaching has a human toll when rangers are killed and communities start to lose the benefits of wildlife tourism and criminal networks start to thrive. "My visit to Namibia this week is focused on conservation. This is an issue very close to my heart, and I know is a matter of deep pride to you all as well," Prince William shared. 

"Your country is famous for its beautiful environment and wildlife. This is the reason why so many tourists, including tens of thousands of Brits, visit every year. Tourism continues to grow year on year and in 2017 accounted for 100,000 jobs — with the potential to add many more. Protecting Namibia's wildlife is crucial to realizing this potential," he continued. While on his trip, William looked over the work of the 'Save the Rhino' campaign in Kunene. 

He also eventually met the members of the local community which was involved in the Kunene People's Park Initiative. After a 5 am start, Prince William accompanied a team of rangers to track a black rhino and saw many other animals on the way. During his speech, he shared that he was "staggered by the beauty and sheer remoteness of this incredible landscape" and "humbled by the dedication of the rangers who protect the unique population of desert rhino from poachers".
