A sherwan or union council in Pakistan is an elected local government body consisting of 21 councillors, and headed by a nazim now called Chairman (which is equivalent to a mayor) and a naib nazim now called Vice Chairman (deputy). Union councils are the fifth tier of government in Pakistan and are often known as Village Councils in Khyber Pakhtunkhwa. A village council usually comprises a large village and surrounding areas, often including nearby small villages. The term Union or Village Council may be used for localities that are part of cities.
