Out of the late Karpal Singh's five children, four of them are involved in politics.

In the 14th General Election (GE14), Gobind's elder brother Jagdeep Singh Deo won the Penang ADUN seat for Datuk Keramat for the third time, while his younger brother Ramkarpal Singh retained the Bukit Gelugor parliament seat previously held by their father.

Meanwhile, according to The Star, their sister Sangeet Kaur is serving as Wanita DAP international secretary and Selangor Wanita DAP deputy chairman.
