British Prime Minister Rishi Sunak and French President Emmanuel Macron came to an agreement on tackling the swath of illegal immigration by way of small boats along the English Channel. 

The deal is expected to cost the UK £470 million ($600 million US) over the next three years. Consequently, Sunak said that the two European countries had gone "further than ever before" in cracking down on illegal immigration across the Channel, according to Evening Standard.

"Emmanuel and I share the same beliefs. Criminal gangs should not get to decide who comes to our countries," Sunak said.

"Within weeks of my coming into office, we agreed our largest ever small boats deal and today we've taken our co-operation to an unprecendented level to tackle this shared challenge," he added. 

Sunak's proposition was initially expected to be turned down by Macron, who accused other EU members, including Italy, of refusing to crack down on stopping illegal immigration into France. Sunak was expected to push for a deal that would be similar to the Dublin Regulation. 

The recent deal includes installing a detention center in France, which will be partially funded by the UK. French personnel will also be involved, equipped with enhanced technology that will be used to monitor beaches, according to the report.
