Gujarat Chief Minister Anandiben Patel on Monday submitted her resignation to state Governor seeking relief from her post in the state. Patel, who took charge as Gujarat’s first woman Chief Minister, posted a letter on her Facebook page. She said that she had two months earlier sought to resign from the party to give “enough time to the new incumbent to prepare for important events like the upcoming Vibrant Gujarat summit”.
