In the wake of a sting operation by a news channel which purportedly shows files being destroyed at the Delhi Secretariat, Chief Minister-designate Arvind Kejriwal today said the matter reflected large-scale corruption in certain departments even as he asked the Chief Secretary to take care of important documents.

"This (the sting) shows there is large-scale corruption in these departments and officials who are seeking transfer are understood to have been involved in it," the AAP leader told reporters here.

In the sting operation, news channel 'Aaj Tak' showed some files being torn up at the Secretariat, which houses the offices of all Delhi ministers, including the chief minister, besides other departments.

Kejriwal said it was the Chief Secretary's responsibility to take care of all the files before a new government took charge.

Kejriwal will be sworn in as the Chief Minister tomorrow along with six other ministers.
