All-islands' collaboration reaps financial benefits.

Every little bit counts:

The UK's 54 police forces hope to save £3.4m every year through a new deal that will see all vehicles branded with a national livery.

Forces looking for a patrol car for beat officers will be restricted to buying from four manufacturers.

The deal includes all English, Welsh, Scottish and Northern Irish forces, the Civil Nuclear Constabulary and British Transport Police.

Maybe even the gardai would be interested in this?

"Through collaboration, we are able to standardise how police vehicles are used across the UK, which means further efficiencies are possible in areas like training and mutual aid."

After all, we're the only other state they share a land border with.
