Around 1,000 police officers from England and Scotland are expected to begin training this month for deployment in Northern Ireland, in case of disorder in the event of a no-deal Brexit.

The Police Service of Northern Ireland (PSNI) have asked for reinforcements to help deal with any trouble that may arise if a hard border forms in the country, according to the Guardian.

Officers will be pulled from their regular duties in order to take part in the training, with some tactics and equipment used by Northern Irish police differing from those used in the UK.

However, the National Police Chiefs' Council (NPCC) told talkRADIO a formal request for mutual aid had not yet been made by the PSNI.

A spokesman for the NPCC said: "Police forces continue to prepare for possible eventualities as exit from the European Union draws nearer. As it stands, we have not received a formal request for mutual aid support from PSNI.

“Forces routinely share officers through mutual aid. When called on, it is used to ensure an appropriate police presence exists where there is increased demand for it."

Mutual aid arrangements are in place to enable local police forces to help each other when demand is heightened.
