Britain will create a new sanctions regime to target the ringleaders of illegal migration networks who facilitate and profit from smuggling tens of thousands of people into the country each year, the government said on Wednesday.
The British government, under huge political pressure to cut the number of people arriving in small boats from France, said the laws would work alongside other reforms to help them target the gangs behind the trafficking.
"With these new sanctions, we will target those profiting off putting lives at risk and disrupt the gangs' finances, making it harder for them to operate," interior minister Yvette Cooper said in a statement.
The policy will be the centrepiece of a speech by foreign minister David Lammy on Thursday, seeking to demonstrate a joined-up approach between the foreign and interior ministries.
The government said the sanctions framework would be in place by the end of the year and give authorities the power to ban targets from entering Britain, freeze assets held in the country, and punish others who are caught trying to do business with them.
