Targeting the Gandhi family, BJP chief Amit Shah said the 'friendship' between Christian Michel, the alleged middleman in the AgustaWestland deal, and the Congress' top leadership is "time tested and deep".
In a series of tweets, Shah also asked if Michel wanted details of his questioning by investigators to be passed onto "Mrs Gandhi".
"Trails of the AgustaWestland Case the SOS of Christian Michel. Does anyone know why Christian Michel passed on the details of questioning on Mrs Gandhi to his lawyer? Did he want them to be passed on to Mrs. Gandhi herself? Why?" he tweeted.
Shah said Michel's lawyer had admitted that the alleged middleman indeed passed paper to him and claimed that he thought it was a list of medicines.
The BJP president took an apparent swipe at the Gandhi family, saying people have heard of Zandu balm and Tiger balm -- medicines used to relieve pain -- but what is this "family balm" that every middleman wants.
"In any case, what must be told again and again is the Congress background of Michel's lawyer. The so called expulsion remains a sham. He remains the conduit between Michel and Mrs Gandhi!" Shah said.
