Reading the situation

Meanwhile, Minister of State for Home R P N Singh, who has held varied portfolios as MoS (corporate affairs, roads, petroleum) appears to have expanded his reading. According to people close to him, he's started reading up on aviation and coal. Is he readying for yet another shift as the elections draw near or is he boning up on issues, already the focus of much controversy, that are about to implode within the corridors of power?
