BJP leaders, especially Yashwant Sinha used to oppose UPA government on its FDI policy, but after coming to power they have allowed 49 per cent FDI in insurance and defence sector, Shukla said.
Shukla, who was Minister of State for Parliamentary Affairs and Planning in the previous UPA government, attacked BJP for speaking different languages while in opposition and in power.
When UPA wanted to bring FDI in these sectors, BJP opposed it tooth and nail, but after coming to power they are speaking the language of UPA government, and exposing their double standards, Shukla said.
He also hit out at BJP's vindictive politics over the I-T notice served to Sonia Gandhi in National Herald case and court summons issued to Rahul Gandhi for his alleged defamatory speech against RSS made during the Lok Sabha elections.
Congress will unitedly fight these allegations in court, he said.
When asked about US President Barack Obama's invitation to Prime Minister Narendra Modi, Shukla said that Modi has been invited only in his capacity as India's Prime Minister and not in his personal capacity.
Shukla was speaking to journalists here on the sidelines of an inspection tour of Kanpur's International Cricket Stadium Green Park.
