Shimla: The newly constituted Himachal Pradesh cabinet today approved lowering the age for providing social security pension, from 80 years to 70 years, along with removal of chairpersons/vice chairpersons and non-official members of boards and corporations with immediate effect. In 2012, Dhumal had won from the Hamirpur seat but this time, the BJP high command asked him to contest from Sujanpur, where Congress candidate Rana has a strong base. When the assembly elections were announced without BJP projecting a chief ministerial face, supporters of Dhumal and Union health minister J P Nadda projected them as chief ministerial candidates.
Earlier, Chief Ministers of Himachal hailed from Shimla, Kangra and Sirmaur districts. In these elections, the BJP won nine out of the 10 assembly seats in Mandi.
