Navjot Singh Sidhu resigned from Capt. Amarinder Singh's cabinet on June 6 after a stormy 27-month tenure as minister. The reason: an apparent demotion with a change of portfolios.

Party insiders say Sidhu's ambitions were fuelled by his wife Navjot Kaur Sidhu, who was in a hurry to see him in the CM's chair. That's right, blame the wife.
