Centre-State relations in India refer to the relationship between the central government and the state governments in the country. These relations are governed by the provisions of the Constitution of India, which defines the powers and responsibilities of both the central and state governments. The principle of federalism is followed in India, where power is divided between the central and state governments.

One aspect of Centre-State relations that has been specifically termed as municipal relations is the Centre's control of the state in the planning process. This refers to the role of the central government in formulating and implementing various development plans and policies at the state level.

Explanation:
- Role of the Centre in the planning process: The central government in India plays a crucial role in the planning process by formulating and implementing various development plans and policies. These plans are aimed at addressing the socio-economic needs of the country and promoting balanced regional development. The central government allocates funds, resources, and grants to the state governments for the implementation of these plans.

- Control of the Centre over the states: In the planning process, the central government exercises significant control over the state governments. It sets the overall framework and guidelines for planning and provides financial assistance to the states. The states are required to align their plans and policies with the national development goals and objectives set by the central government.

- Devolution of funds: The central government also plays a crucial role in the devolution of funds to the states. It allocates funds to the states based on various factors like population, area, and backwardness. The states are required to utilize these funds as per the guidelines and conditions set by the central government. The central government also has the power to monitor and evaluate the utilization of funds by the states.

- Planning Commission and NITI Aayog: Earlier, the planning process in India was overseen by the Planning Commission, which was a centralized body under the control of the central government. However, in 2014, the Planning Commission was replaced by the NITI Aayog (National Institution for Transforming India), which is a think tank that provides policy inputs and strategic advice to the central and state governments. The NITI Aayog continues to play a key role in the planning process and maintains a close relationship with the state governments.

- Significance of Centre-State planning relations: The central government's control over the state governments in the planning process ensures coordination, coherence, and uniformity in the development efforts of the country. It helps in addressing regional imbalances, promoting inclusive growth, and ensuring that the national development goals are achieved. The Centre-State planning relations also facilitate cooperation and collaboration between the central and state governments, leading to better policy formulation and implementation.

In conclusion, Centre-State relations in the planning process can be specifically termed as municipal relations because of the Centre's control over the state governments in formulating and implementing various development plans and policies. This control ensures coordination, coherence, and uniformity in the development efforts of the country and helps in achieving the national development goals.
