Solanki will hold the additional charge of Punjab till a regular governor for the state is appointed.
Chief Justice of Punjab and Haryana High Court S.J. Vazifdar administered the oath of office to Solanki at Punjab Raj Bhavan here.
He will also hold charge of administrator of union territory of Chandigarh.
The five-year term of Punjab Governor Shivraj Patil ended Wednesday. Patil, a former union home minister, joined here as governor Jan 22, 2010.
Patil’s tenure remained largely non-controversial but lacklustre, especially in the context of Chandigarh’s development.
