Just four months ahead of the Assembly polls in Punjab, Congress veteran Amarinder Singh on Saturday stepped down as chief minister, citing "humiliation" after a section of MLAs sought a change in state leadership "for the third time in recent months".

With the captain's resignation, speculations on who would be at the helm of the Congress party have started to grow. Former Punjab Congress president Sunil Jakhar has emerged as a frontrunner amid reports that the party wants to project a non-Sikh chief ministerial face ahead of polls to counter AAP, which is gaining ground in the state.
