Briefly explain about the Indian Administrative Service (IAS) and the Indian Police Service (IPS)

What will be an ideal response?

India is unified by a national administrative cadre. There was a debate after
independence over whether to abolish the elite national civil service and police forces,
the Indian Civil Service (ICS) and Indian Police (IP), which occupied virtually all the senior
positions at both the federal and state level. Many Congressmen saw these services as
stooges of the British, and as representatives of a "colonial" style of government that
could not be reformed. However, Congress ultimately decided that these services had to
be kept as a unifying influence, even though the ICS and IP were renamed the Indian
Administrative Service (IAS) and the Indian Police Service (IPS). The higher positions in
each state's police force and civil service must be members of these nationally recruited
forces, who alternate between posts at the center and in the states, and who cannot be
fired by the state governments without the permission of the Indian president. The IAS
is the most elite and prestigious all-India civil service. It is recruited mainly through a
national and very competitive annual examination.
