Taking a swipe at Leader of the Opposition in the Lok Sabha and Congress leader Rahul Gandhi, Union Minister Amit Shah has said that a "54-year-old masquerading as a young leader" alleges that attempts are being made to alter the Constitution without realising that provisions to do so are built into the document. Mr Shah, who was speaking in the Rajya Sabha on Tuesday during a debate to commemorate 75 years of the Constitution, was referring to Rahul Gandhi and the Congress' allegations that the BJP wants to amend the document and dilute its character - a move that paid dividends for the party and the opposition INDIA bloc during the Lok Sabha elections.
