Kaur had tendered her resignation to Chief Minister Parkash Singh Badal who subsequently forwarded it to the Governor for its acceptance, a spokesperson of the Chief Minister's office said here.
57-year-old Kaur, who held portfolios of Rural Water Supply and Sanitation and Defence Services Welfare, was sentenced to five years' imprisonment by the CBI court for conspiring in forcible abortion and abduction in connection with the mysterious death of her teenage daughter Harpreet Kaur 12 years ago.
The senior Punjab Minister was the lone woman member in the 18-member Parkash Singh Badal-led SAD-BJP ministry sworn in last month.
