Answer: A regional party is a political party whose influence is limited to a particular state or region.
Such parties usually take up the language, culture, traditions or local problems of that region. Examples are the Shiv Sena and the Nationalist Congress Party in Maharashtra, the Dravida Munnetra Kazhagam and the All India Anna Dravida Munnetra Kazhagam in Tamil Nadu, the Telugu Desam in Andhra Pradesh and the Akali Dal in Punjab. A party is recognised as a state party by the Election Commission on the basis of its performance in that state, and regional parties often influence national politics through coalitions.
