HUDDERSFIELD MP Barry Sheerman has welcomed a drop in violent crime.
And he said the news allayed fears that longer licensing hours would lead to problems.
Mr Sheerman praised West Yorkshire Police for the operations they mounted in December and January, which helped lead to a 17% drop in crime figures.
The blitz on alcohol- related disorder also meant that violent crime in Kirklees fell by more than 20% in the last six months of 2005.
Mr Sheerman said: "There were many scare stories that the new Licensing Act would lead to an increase in drunk and disorderly behaviour and violent crime.
"I am pleased that initial figures and anecdotal evidence shows that the staggered closing times made it easier for the police to manage drunk and disorderly behaviour."
Mr Sheerman made his comments after a meeting with police divisional commander Chief Supt Barry South.
The MP added: "I meet regularly with Chief Supt South to discuss problems that constituents have contacted me about.
"It is also a useful opportunity to hear about local policing issues."
A national six-week campaign, which began in November last year, focused on tackling alcohol-related behaviour and targeting those selling alcohol to children.
During the campaign, police and trading standards officers across the country carried out more than 6,000 test purchase operations, dealt with more than 30,000 offences and made over 25,000 arrests.
