Kayveas was born on 29 April 1954, in Benta Estate, Kuala Lipis, Pahang, Malaysia. He is married to Blanche Olbery, formerly a Malaysian Ambassador to the Republic of Finland, and has four children: Marsella Kayveas, Yasheena Kayveas, Mikhaerl Kayveas and Mikhryan Kayveas.

Kayveas was a Flight Attendant and Pilot with Malaysia Airlines.

In 1993, Kayveas became president of People's Progressive Party (PPP), a component member of the ruling coalition Barisan Nasional, and is the longest serving PPP president to date. He was credited for putting the PPP on a strong footing after many years of internal strife within the party. Membership of the PPP in the coalition was suspended from 1988 until 1993. When Kayveas started restructuring the party and brought it back to the coalition in 1994, many old timers who caused the party's internal squabbles wanted to take back the helm and push Kayveas out. However, he emerged victorious and worked on growing the party and regaining its past glory. Today, the PPP is 574,000 strong with a network of over 3700 branches throughout the country. The restructure started with Kayveas himself having a membership card signed by the secretary-general as #000001 and all subsequent cards are personally signed by Kayveas as president himself. It is also understood that the Malaysian Book of Records is notified and it would be registered as the most number of signature of sorts.

Kayveas who was formerly known as K.V.S was a born Hindu. Kayveas is a graduate from University of Buckingham,^{[citation needed]} Buckingham, England.

Kayveas was a Deputy Minister in the Prime Minister's Department, which is a ministry by itself. Kayveas previous responsibilities as a deputy minister includes:

• Pardon's Board
• Attorney General's Chambers
• Legal Affairs Division
• Legal Aid Bureau

In July 2007, Kayveas was alleged to have mentioned an ultimatum to leave the Barisan Nasional coalition if the ISA is not amended and his party is not given any allocation of seats in the next general election. He later clarified that there was no such thing as an ultimatum but simply stating the PPP's stand and made a 'friendly request' on the seats .^[1]
