In legislature, the Opposition Party has a major role and must act to discourage the party in power from acting against the interests of the country and the common man. They hustle to present themselves as a suitable alternative government.
Following are the three functions of opposition parties :

(ii) Their role is toensure that the government should not take any step which is against the interest of the public.
(iii) Their duty is to check and ensure that the action of the ruling party is for the benefit of the masses and to support the government in such things. They, thus, facilitate formation of public opinion and are a way in which the schemes of government are checked and communicated to the public.
