MP Anurag Thakur on Friday took a swipe at the Congress leadership, saying "a senior Congress leader recently met AgustaWestland middleman Christian Michel in Dubai" and asked if the Union government knew about it.Taking up the AgustaWestland issue in the Lok Sabha, Thakur said: "Recently a senior Congress leader went and met Christian Michel in Dubai... does the Union government know about it?"He also made a veiled attack on Congress president Sonia Gandhi by saying that "her name was mentioned four times in the Italian court judgement" on the AgustaWestland chopper deal."There was one name which came up four times in the Italian judgement. Without taking the name there is so much pain. If I take the name, I don't know there will be how much pain among the Congress leaders," Thakur said.
