The Shiromani Akali Dal quit the National Democratic Alliance (NDA) over farm bills, but strains in relations between the two oldest allies had begun surfacing for over a year.
Later, in first signs that all was not well between the two allies, the SAD opted out of contesting this year's Delhi assembly polls.
Another BJP leader and former minister Master Mohan Lal had then said the saffron party should go alone in the 2022 assembly polls.
Over the years, the SAD-BJP had settled seat-sharing formula in the state, with the saffron party contesting on 23 seats and Akalis on 94 seats in assembly polls.
Akali stalwart and former chief minister, Parkash Singh Badal used to describe ties with the BJP as 'nau-mass da rishta' (ties like nail and flesh).
