Explain All-India services and their implications.
All-India services refer to the administrative services of India that are common to both the central and state governments. These services, including Indian Administrative Service (IAS), Indian Police Service (IPS) and Indian Forest Service (IFS), provide a pool of officers who can be appointed by the central government to serve in any part of India or by the state governments for service within their respective states.

The implications of All-India services include:

1. Uniformity and standardization of administrative practices across different states, leading to better governance.
2. Mobility of officers between central and state governments, enabling them to gain diverse experiences and perspectives.
3. A career growth opportunity for talented officers to serve at both the national and regional levels.
4. Opportunity for central government to have direct control over administrative matters in states, as they can appoint their own officials to key positions.
5. Potential conflict of interests when state-level issues are addressed by centrally-appointed officers who may not be fully attuned to local concerns and priorities.
