The Bharatiya Janata Party's (BJP) president, Rajnath Singh, spoke of a "political conspiracy" aimed at the "vilification of Hindu saints and army officers in the name of Hindu terrorism".[25] In 2010, the internet whistleblower organisation WikiLeaks released US embassy cables in which the US ambassador to India scornfully dismissed suggestions by an Indian minister that the death of Hemant Karkare, a senior anti-terrorism investigator killed by Islamist militants during the 2008 Mumbai attacks, was somehow orchestrated by Hindu extremists. The term "saffron terror" was prominently used by some Congress party members in this campaign, most prominently by Digvijaya Singh.[26][27] The BJP criticised these statements and filed a complaint with the Election Commission of India, citing it as a violation of the Model Code of Conduct for political parties. The Election Commission issued a show-cause notice to Digvijay Singh on this complaint.[28] The Hindu spiritual leader Sri Sri Ravi Shankar has also criticised it, saying that it is a myth and insult to the Hindu religion, which he said is the most tolerant religion.[29]
