For the BJP, his presence would have been of immense help when it is battling it out so hard in Punjab in the face of protests and disruptions by some farmers’ groups. If Amarinder were in action, the farmers may have thought twice about opposing the BJP, since he (Amarinder) has always been known to be a pro-farmer leader. 

The ruling family has continued the political tradition in the post-independent India also, first through Maharaja Yadvinder Singh, a great nationalist, who had a great role supporting Sardar Patel in a great way to unify all the princely states, and continued by his son Capt Amarinder Singh, who rose to become the Chief Minister of Punjab twice.

Kaur, who is the wife of ex-Punjab Chief Minister Amarinder Singh, joined the saffron party at BJP's headquarters.  

Speculations are that Kaur will be fielded from the same Lok Sabha seat - Patiala, which she held since 1999 (13th Lok Sabha election), despite earlier considerations favoring Jai Inder Kaur.
