New Delhi, March 14 (IANS): The Congress party on Saturday condemned Delhi Police's "unnecessary and weird enquiries" about party vice president Rahul Gandhi and termed it "political espionage".

"This kind of political espionage, snooping, surveillance and intrusion in political opponent's life may be Gujarat model but not Indian model," party spokesperson Abhishek Singhvi said, referring to the oft-quoted Prime Minister Narendra Modi's Gujarat model of development.

According to reports, the police visited the Congress office last week and asked about Gandhi's physical appearance - his height, colour of eyes and hair.

The police said it was a routine enquiry.

"A few days ago, an ASI from Delhi Police headquarter was found snooping, making unnecessary and weird remarks at Rahul Gandhi residence. When stopped by SPG, it was found he was trying to fill up a form with weird questions about Rahul Gandhi's height, colour of eyes, hair," Singhvi said at a press conference here.

Targeting the central government, Singhvi said: "India is a proud democracy, not a police state. We are a vibrant democracy. This kind of political espionage is condemnable."

The Congress demanded an explanation from the home minister or the prime minister.

"We demand a comprehensive explanation by no less than home minister or prime minister, its not a Congress centric issue, it affects all political parties."

"We will be taking up this issue in parliament," he added.

On the other hand, police said such surveys are conducted at all protected persons' offices from time to time and no personal questions were asked.
