An additional £100million in funding to deter Channel crossings has been announced by the Home Office.
The money will see up to 300 more National Crime Agency (NCA) officers and new technology created to crack down on illegal people-smuggling.
Home Secretary Yvette Cooper said the move would help the UK better "track the [smuggling] gangs and bring them down".
The Conservative Party has called the plans a "desperate grab for headlines which will make no real difference".
More than 25,000 people made the journey from France to the UK in small boats before the end of July, and last month the government agreed a "one in, one out" policy to deter migrants from crossing the English Channel.
Under the pilot scheme, some arrivals would be returned to France and the UK would accept an equivalent number of asylum seekers in exchange.
