If he is not, then why he is worrying,' said Dhumal, further infuriating the Congress members who alleged that this was a conspiracy to defame the former chief minister.

On Singh's allegations that his phones are being tapped by the state government, Dhumal replied: 'The state government has no control or access to landline and mobile phones of people. These come under the purview of the telecom ministry.

'If he (Singh) is not satisfied, he should get the matter (phone tapping) investigated by the Central Bureau of Investigation. I even urged Prime Minister Manmohan Singh to investigate the charges levelled by Singh against the state government.'

Singh Wednesday charged the state machinery of tapping his phones. He said he would write to Union Home Minister P. Chidambaram to inquire into the matter.

The cases against Singh and his wife were registered Aug 3 by the state vigilance and anti-corruption bureau under the Prevention of Corruption Act, 1988. The complaint against Singh was alleged misuse of his official position and criminal misconduct when he was chief minister in 1989.

Singh, a five-time former chief minister, reached here for this weeklong tour Tuesday.
