The party launched the campaign on Twitter under the theme "#UTurn Sarkar".
The first hashtag "#BJPBlackMoneyDhokha" was posted on the wall of AICC Communication Department Chairman Ajay Maken's Twitter account in the morning.
It began with a catch phrase "six months have passed; It's U-turn Government (chheh mahine paar; U-turn Sarkar).
The AICC leader had yesterday tweeted about the campaign alleging that the BJP government at Centre has "performed at an average, one #UTurn every week".
The party has, for last few months, been attacking the NDA government over the issue of blackmoney and rise in food price basket from time to time besides accusing it of failing on economy as well as foreign affairs front.
