Britain has agreed to pay France tens of millions of pounds more to stop people making dangerous Channel crossings, but Rishi Sunak has admitted the problem may still persist.
A 72 million euro (£63 million) deal, signed on Monday morning, will see a 40% increase in the number of officers patrolling beaches along the French coastline in the coming months.
For the first time, British border staff will be stationed in control rooms on the other side of the Channel to observe operations.
