Singh has been at the centre of controversy ever since the row over the four year undergraduate programme (FYUP) broke out, with HRD ministry under Smriti Irani directing him to roll back the programme in June last year as it had no approval from the President who is the Visitor to Central universities.
In his letter, Yechury has also mentioned about a 'white paper' released by Delhi University Teachers Association (DUTA) alleging grave illegalities, academic erosion and administrative breakdown due to abuse of office by the VC.
HRD ministry officials said that the Minister has forwarded Yechury's letter along with a host of other documents to Rashtrapati Bhavan in December last year but was yet to receive a response.
"We have received no communication from the President after the Ministry sent the documents to the President last month," said a senior HRD ministry official.
Sources however said the Rashtrapati Bhavan was closely monitoring the developments in Delhi University and was examining the charges against Singh.
