New Delhi, Sep 22 - Home Minister P. Chidambaram Tuesday told citizens of Delhi that they needed to change some of their bad habits if visitors to the Commonwealth Games next year are to have a good impression about the host city.

'We cannot expect mega city policing to function properly if people do not change their behaviour. We still find vehicles jumping red lights - and police vehicles are not excluded, they too jump red lights,' Chidambram said after inaugurating 22 new police stations in the capital at a function.

'There are vehicles running without registration plates, some are crossing roads where they should not. People are not using overground or underground passes. We want to encourage people to change their mindset,' he said.

Germany during the Football world cup 2006 and China during the Beijing Olympics 2008 had carried out massive exercises to change behaviour of their citizens, the minister added.

'People come to Delhi. This is the capital and we cannot stop people. But if they come to Delhi, they themselves will have to adhere to the behavioural requirement. We must behave as a citizen of a big, good international city,' Chidambram said.

Delhi Chief Minister Sheila Dikshit took the cue and said a campaign will soon be launched to make people in the national capital aware about the need for behavioural changes.
