This is one important similarity between the British and the Indian Constitution.

Britain has a Parliamentary form of government. The King, who is sovereign, has been deprived of all his powers and authority. The real functionaries are Ministers, who belong to the majority party in the Parliament and remain in office as long as they retain its confidence.

The Prime Minister and his Ministers are responsible to the legislature for their acts and policies. Parliamentary system is based on the principle of collaboration and cooperation between the executive and legislative organs. The executive in British has individual legal responsibility whereas in India there is no legal responsibility.
