Congress leader Rahul Gandhi on Saturday threw his weight behind the protests against alleged irregularities in BPSC exams, by visiting the site of the nearly a month-old agitation here and spending several minutes with aggrieved students. After Gandhi winded up his pre-decided engagements, during which he also made a veiled reference to the protests with the remark "Bihar has been converted into a centre of paper leaks", a delegation of students called on him at a hotel. The delegation urged him to visit Gardani Bagh where several aspirants have been on a round-the-clock protest seeking cancellation of Combined Competitive Exam held last month. Suman Saurabh, a student from Sitamarhi, who was part of the delegation, told PTI video, "We urged Rahul Gandhi to visit Gardani Bagh which is our 'dharmabhoomi' and 'karmabhoomi'. He said he will take some time off. As the Leader of the Opposition in the Lok Sabha, he is known to the entire nation and his support means a lot to us." Gandhi
