Both Houses of Parliament adjourned

Amid ruckus, Rajya Sabha was first adjourned for 15 minutes and then till 12 noon following an uproar over the bugging row.

Union Home Minister Rajnath Singh said the reports on bugging are untrue.

Amid chaos, Speaker Sumitra Mahajan adjourned the Lok Sabha till 12 noon.

Union Transport and Rural Development Minister Nitin Gadkari, who was earlier the president of the ruling Bharatiya Janata Party (BJP), had earlier this week called as speculative the reports that bugging devices were found in his Delhi residence even as reports said the Union Home Ministry has ruled out any probe into the matter.

The Union Home Ministry had ruled out a probe.

Former Prime Minister Manmohan Singh however speaking to a news agency demanded a probe calling it a bad omen.

Earlier a report in The Sunday Guardian said  high power listening devices were found in the bedroom of Nitin Gadkari at his 13 Teen Murti Lane residence in New Delhi. The discovery was "accidental" and a debugging exercise was immediately ordered.

The paper edited by well known journalist turned BJP leader  MJ Akbar, who is a party spokesperson, quoting "highly placed sources", said more devices were consequently discovered at the residence of the senior BJP leader who is also the Union Minister for Road Transport & Highways. Gadkari has apparently informed Prime Minister Narendra Modi and Rashtriya Swayamsevak Sangh (RSS) chief Mohan Bhagwat about the incident, it reported.
