Sir — This refers to the article, “Playing with Constitution and prospering too”, by A Surya Prakash (June 20). On the 42nd anniversary of the Internal Emergency imposed by then Prime Minister Indira Gandhi on June 25, 1975, replacing democracy with her dictatorship, the writer has reminded us of 21 months of tyranny, deprivation of fundamental rights and free expression. It was an unprecedented occurrence and a terrible black chapter.
