Prime Minister Narendra Modi must speak to parliament about his decision to suddenly cancel 500-and-1,000 rupee notes, the opposition insisted today, remaining united around its attack on the currency ban. "The PM can speak on television, at a pop concert, but not to parliament," complained Rahul Gandhi, the 46-year-old Vice President of the Congress, referring to the PM's opening remarks at the Coldplay concert in Mumbai over the weekend, where Mr Modi, through video conference, quoted a verse from Bob Dylan's "The Times They Are A Changin'."
