Congress candidate from Himachal Pradesh's Kangra Lok Sabha seat Anand Sharma on Monday accused the BJP of trying to disprove history and insulting the nation builders as he asserted that Manmohan Singh left a strong India and a stout economy in 2014, reported news agency PTI.

At an election rally in Churah of Chamba district, he also lashed at the BJP-led Centre for its "step brotherly treatment" towards the hill state during last year's monsoon disaster.
