The Indian Constitution closely follows the constitutional system of the United Kingdom. This is because India was a British colony for over 200 years, and the British system of government was familiar to the Indian people.

Some of the key features of the Indian Constitution that are based on the British system include:

• The parliamentary system of government: The Indian government is a parliamentary democracy, with a Prime Minister who is the head of government and a President who is the head of state. This system is similar to the system of government in the United Kingdom, where the Prime Minister is the leader of the majority party in Parliament and the Queen is the head of state.

• The rule of law: The Indian Constitution guarantees the rule of law, which means that everyone is subject to the law, regardless of their position or status. This principle is also enshrined in the British Constitution.
• The separation of powers: The Indian Constitution establishes a system of separation of powers, with the executive, legislative, and judicial branches of government being kept separate. This system is similar to the system of government in the United Kingdom, where the executive branch is headed by the Prime Minister, the legislative branch is the Parliament, and the judicial branch is the Supreme Court.

The Indian Constitution also incorporates some features that are not found in the British Constitution, such as:

• The Directive Principles of State Policy: These principles are a set of guidelines for the government to follow in order to promote the welfare of the people.
• The Fundamental Rights: These rights are guaranteed to all citizens of India and cannot be taken away by the government.

The Indian Constitution is a living document that has been amended several times since it was first adopted in 1950. However, the basic structure of the Constitution remains the same, and it continues to be based on the constitutional system of the United Kingdom.

In addition to the United Kingdom, the Indian Constitution has also been influenced by the constitutions of other countries, such as the United States, Canada, and Australia. However, the British system of government has had the greatest influence on the Indian Constitution, and it continues to be the foundation of the Indian government today.
