Amid the raging controversy over release of a Kashmiri separatist leader, Indian Union home minister Rajnath Singh yesterday asserted that his government's top priority was national security and not the continuance of the government in the state where BJP is an alliance partner.

His remarks come a day after Narendra Modi made it clear in Parliament that release of separatist leader Masarat Alam was not acceptable and that the government won't tolerate any compromise with the nation's integrity.

Singh maintained that he was not satisfied with the official version that the state government sent to his ministry earlier on this subject.
