Revellers were urged to ‘pace themselves’ as up to 300,000 flood into Manchester for Mad Friday.

Police were bringing in extra officers to cope as offices close early and staff go out on festive works parties.

Phil Burke, spokesman for the Manchester Pub and Club Network, which represents over 600 licensed premises, said: “Have a good time and enjoy the atmosphere but drink sensibly and in moderation.

“There are extra bar and door staff. If you’re out early, remember to pace yourself and make sure you book a registered taxi to get home.”

About 30 officers will be on duty during the day as an estimated 100,000 people come into the city to enjoy the shops and markets.

A further 100 officers will come on duty during the evening when 150,000 to 200,000 people are expected.

Police have vowed to crack down on any trouble early in the day to prevent any problems later in the evening.

Crack Tactical Aid unit riot officers and mounted police will be on hand during the high-profile operation.

Business leaders estimate the Mad Friday spending bonanza could be worth £15m to the city.
