Explanation:

The First Past the Post (FPTP) system of election within the Indian Constitution is borrowed from the British Constitution.

Reasons:

1. Historical Background: India was under British colonial rule for nearly 200 years, from the 18th century until 1947 when it gained independence. During this period, the British established various political institutions in India, including the electoral system. As a result, many features of the British political system were adopted by India, including the FPTP system of election.

2. Influence of the British Parliament: The Indian Constitution, which was adopted in 1950, drew heavily from the British constitutional framework. The framers of the Indian Constitution were influenced by the British parliamentary system, and they incorporated several elements of it into the Indian political system. One such element is the FPTP system of election.

3. Familiarity and Ease of Implementation: The FPTP system was already well-established and widely understood in India during the time of independence. It was the system that had been used by the British in India, and it was familiar to the Indian political leaders who were involved in the drafting of the Constitution. Adopting the FPTP system made the transition from British rule to independent India smoother and easier.

4. Compatibility with Indian Diversity: India is a vast and diverse country with numerous regional and cultural differences. The FPTP system is simple and easy to understand, which makes it suitable for a country with such diversity. It allows for direct representation of constituencies and ensures that the elected representatives are accountable to their constituents.

In conclusion, the FPTP system of election within the Indian Constitution is borrowed from the British Constitution due to historical reasons, the influence of the British Parliament, familiarity and ease of implementation, and compatibility with Indian diversity.
