Amid growing demands for 'one-rank-one-pension' for ex-servicemen, Rahul Gandhi will now be taking up their cause. At least that's what the Cong scion promised when he met representatives of former military personnel and war widows at the Congress headquarters a shortwhile back. The demand of the soldiers was accepted by the UPA government and announced again by the NDA government after it came to power last year. The UPA government had even allocated Rs 8,300 crore budget for the scheme. But the soldiers are yet to get the benefits. Congress leaders said that ex-servicemen are unhappy over the non-implementation of the scheme.
