Perak is ethnically, culturally and linguistically diverse. The state is known for several traditional dances: "bubu", "dabus", and "labu sayong", the latter name also referring to Perak's unique traditional pottery. The head of state is the Sultan of Perak, and the head of government is the "Menteri Besar". Government is closely modelled on the Westminster parliamentary system, with the state administration divided into administrative districts. Islam is the state religion, and other religions may be practised freely. Malay and English are recognised as the official languages of Perak. The economy is mainly based on services and manufacturing.
