Singh has written the letter on his personal letterhead bearing his Bhopal address. Tewari spoke in similar vein when asked whether the four-page letter in which Singh has cautioned Hazare against "lofty promises" by BJP of making him a Presidential candidate, was his personal view. "I do not want to respond to any further queries on the issue," he said when asked whether the letter by Singh, a vocal critic of Team Anna, was being treated by the Congress like a "non-paper" in diplomatic terms.
With Team Anna campaigning against his party in Hisar by-poll, Singh dashed off the letter to Hazare asking why he was "silent" on the issue of corruption when the BJP-led NDA was in power. "What is being seen now is that you have been strongly opposing the Congress and as against this you have been praising BJP`s Narendra Modi despite the fact that there is no Lokayukta in Gujarat for the past nine years," Singh said in his letter written just two days ahead of the by-poll. Replying to a query, Tewari questioned whether corruption was really the focus of the Team Anna campaign in Hisar or the reference point was "anti-Congressism".
