British police are to mount a 2.3-million-pound (about 4.2 million US dollars) security operation at this year's ruling Labor's annual conference to prevent possible terror attacks, local media reported Sunday.

More than 1,000 police will take part in Operation Otter in and around at the Brighton Center, southern England, providing security for ministers and delegates at the event, scheduled between Sept. 26 and 30, a BBC report said.

Pontoon-shaped barriers made of steel and encased in concrete will be placed around a sealed site that will include two hotels and the conference center so as to make sure no vehicle can be driven into the area.

The two hotels will be connected to the conference center by a specially constructed bridge. The adjacent multi-storey will be shut to members of the public and searches of the surrounding car parks conducted.

Special checking points and extra power supplies will also be introduced before and during the conference and police will be able to close all roads in the city at short notice should a security threat emerge.

An air exclusion zone will be enforced but there will be no seaexclusion area.

"Brighton will be a very safe place to be during the conference," said Chief Superintendent Jeremy Paine, adding that there is no specific information about a threat.

"However, if something does become known, we will be ready for it. We have in place a no compromise approach to security," he wasquoted as saying.
