The Delhi government has not opposed the death sentence to parliament attack convict Afzal Guru but expressed concerns of law and order if he is executed, official sources said.

Delhi government Tuesday forwarded the file on Guru's mercy petition to Lieutenant Governor Tejendra Khanna with its suggestions. Khanna's office later returned the file to the state home department, government sources said but did not give any details.

Official sources said the state government has not opposed the death sentence awarded to Guru by a trial court in December 2002.
