With expelled BJP leader Jaswant Singh attacking the party, Congress on Saturday said "unsavoury details are coming out of the dirty linen being washed" by BJP in public.
"A lot of extremely unpleasant and unsavoury details are coming out of the dirty linen that is being washed by the BJP in public," party spokesperson Jayanthi Natarajan said.
She described the "revelations" by Jaswant Singh as shocking.
Singh has claimed former Home Minister LK Advani had stopped Atal Bihari Vajpayee from taking action against Gujarat Chief Minister Narendra Modi over the 2002 riots in the state on the ground that it could trigger an uproar in the party.
Congress has accused BJP adopting different yardsticks for Advani and Jaswant Singh both of whom had drawn flak for their comments on Pakistan founder MA Jinnah.
"It is clear that they have double standards for LK Advani, Jaswant Singh and for Arun Shourie," Natarajan had said yesterday.
