French officials have consented to begin stopping migrant vessels in the Channel, following an extended period of pressure from the UK.
The change in policy comes after the Prime Minister sent a letter to the French leader asking him to support the plan and saying there currently "lack any effective preventive measure" in the Channel.
French maritime police will be allowed to intercept the small boats at sea, but only before they've collected their passengers, according to official confirmation.
French authorities have rarely intervened to prevent the heavily loaded boats departing from the coastline because it is considered too great a risk to both officers and individuals.
"It is crucial that we deploy these tactics this period... We have no effective prevention in the Channel waters."
Currently, a French maritime police representative states officers will start intervening at sea, with the aim of protecting human life.
Significantly, the official ruled out the use of entanglement devices to intercept boats, which had previously been reported as a possible technique to snarl the engines of the vessels.
The decision to take action at all is a significant step forward, coming after a short-lived change towards a stricter strategy this warmer season, which ceased when the former Interior Minister departed from government.
That was highlighted in July, preceding a meeting between the Prime Minister and President, when French police were observed walking into the sea to slash the hulls of a boat.
Now French authorities will once more be allowed to intercept boats before they pick up asylum-seeking individuals from the beaches of France's north coast, however it's uncertain how the small boats will be stopped.
Powerful gusts are presently postponing the commencement of interceptions and the people-smuggling networks will be looking for ways to adjust to evade detection, as they have done so often in the previous instances.
The Home Office and Downing Street have been contacted for comment.
