Senior Bharatiya Janata Party (BJP) leader Yashwant Sinha on Friday alleged Union Finance Minister P Chidamabaram had ordered his telephones and that of his family be tapped after he weighed in on the Aircel-Maxis row, implicating the former Home Minister.
"Today, with complete responsibility, I want to say that when I raised the issue of Aircel-Maxis, Chidambaram ordered to tap my phone as he was then Home Minister," Sinha said.
"This shows the Congress vindictiveness, but BJP will not succumb to such pressure or threats," he said, labelling it as a way to pressurise him.
Neither Chidambaram, nor the Home Ministry, which is now headed by Sushil Kumar Shinde, commented have commented on accusation so far.
Sinha's allegations refer to charges levied against the Finance Minister by his party that he deliberately delayed permission for the sale of the telecom Aircel to a company named Maxis from Malaysia.
The move purportedly allowed Chidambaram´s son to invest in Aircel and benefit from Maxis´ acquisition of the company.
Chidambaram has strongly denied the accusations in Parliament, saying "It would be much simpler if somebody took a dagger and plunged it into my heart, rather than questioning my integrity."
Neither he nor any members of his family have owned "any share in any telecom company at any time, indirectly or directly", the senior Congress leader has said.
