A group of AAP leaders who on Tuesday visited Delhi University to check Prime Minister Narendra Modi's B.A. degree said they had been asked to return on Wednesday.The university authorities, however, did not allow Aam Aadmi Party leaders Ashutosh, Sanjay Singh, Dilip Pandey and Ashish Khetan to meet Vice Chancellor Yogesh Tyagi. Khetan said at the campus that they were told that Tyagi was busy and that they should return on Wednesday. He told the media at the university that they reached the campus because "it is a matter of the Prime Minister's degree and it is the VC's responsibility to present the truth".Police personnel reached the site in large numbers. Later, the AAP leaders left.On Monday, BJP president Amit Shah and Finance Minister Arun Jaitley presented Modi's B.A. and M.A. degrees and accused Delhi Chief Minister Arvind Kejriwal of telling lies on the issue.The AAP, however, pointed out what it said were anomalies in the marksheets accompanying the B.A. and M.A. degrees while Kejriwal insisted that the degrees shown by Shah and Jaitley were fake.
