Nikhil is the son of Karnataka Chief Minister HD Kumaraswamy.
In February this year, Sumalatha made headlines for declaring that she would contest Lok Sabha elections from Mandya - a seat her husband had represented both as Member of Parliament and Member of Legislative Assembly. MH Ambareesh passed away in November last year.
On March 18, Sumalatha announced that she would contest from Mandya parliamentary constituency as an independent candidate in the Lok Sabha elections after Congress gave the seat to JD(S) as a part of the seat-sharing deal finalised between two alliance partners.
BJP had supported her by not fielding any candidate from the Lok Sabha seat.
The BJP-led NDA is comfortably set for a return to power at the centre with the alliance in a comfortable lead on about 340 Lok Sabha seats in the country.
