In a dramatic intervention, Mr Johnson wrote directly to the French president to formally offer hundreds of British personnel to stop desperate migrants from taking to the water.
France has so far fiercely resisted any move to allow British law enforcement officers to operate on its soil, claiming it would violate French sovereignty.

He also proposed greater intelligence sharing and the use of more advanced technology, including ground sensors and radar to detect migrants before they leave France.
In addition, he urged Paris to negotiate a ‘returns agreement’ that would allow the UK to send migrants back to France, breaking the traffickers’ business model.
