Followers of the Ford Kenya deputy party leader were shocked at how young the mother of two looked.

Some of the commentators were curious about her age and how long the two had been together.

The normally outspoken politician, however, did not indulge the awestruck inquirers neither did he offer up any further explanations.

Dr Khalwale had shared the photos of his wife while congratulating her on her graduation.

Mrs Khalwale graduated at the KCA University on Friday with a Masters Degree in Business Administration.

"Once again an academic moment in my great family as my wife, Diana, graduates with an MBA today at the KCA University," Khalwale's post read in part.

He also thanked her wife's employer for giving her support as she pursued her studies.

Here are some of the replies Boni received.

Polygamous Family

Aside from Diana, Khalwale is also married to Adelide and Jospehine with whom he also has children.

The former Senator married his first wife while he was still at the university, in second year.

"We were given a Sh1,500 stipend, which was quite a lot then. Life as such was relatively easier, and I could even afford to marry while in second year. However, my marriage nearly collapsed, since girls would hang around me because I was a politician and the medical school students’ representative. Well, taking a tough course was probably also an attraction.

"I nonetheless stuck to my girl who is today my wife. At the time, she had dropped out in form two because of me. I however made sure she went back to class and is currently working at a local university," he said in a past interview.
