62-year-old Singh, who was elected from Lucknow Lok Sabha constituency, will succeed Sushilkumar Shinde in the crucial Ministry that handles country's internal security and the task of guarding the international border with Pakistan, China, Bangladesh, Nepal and Bhutan.
As Home Minister, the two-term BJP president will be part of Prime Minister Narendra Modi-led Cabinet Committee on Security, the country's highest decision making body on security matters.
