Fast-food chain KFC has admitted breaching hygiene rules at one of its busiest branches in Britain.

The chain admitted having inadequate pest control at the branch in London's Leicester Square during a hearing at Westminster Magistrates' Court.

City of Westminster Council said cockroaches, mice and flies were found during an inspection of the premises in Coventry Street in August 2008.

KFC also admitted failing to provide hand-washing facilities.

The company also admitted failing to keep the restaurant clean and in good order.

After the hearing, KFC spokeswoman Nina Arnott said: "These charges date back to August 2008 and, as soon as we were made aware of the results of the inspection, we took immediate action to bring the restaurant back up to our strict hygiene standards."

Ms Arnott said a new manager had been installed and the restaurant had performed well in recent inspections. The restaurant has also undergone a complete renovation, she said.

Eight other allegations against the fast-food chain were dropped.

They included an allegation that food was not protected against contamination because dirty cloths were used to wipe preparation surfaces and chicken racks were covered in congealed fat.

The case was adjourned for sentencing until 10 May.
