Former police chief Martin Hewitt has been appointed to head Britain's new Border Security Command, which will focus on tackling small boat crossings.
As chairman of the National Police Chiefs Council (NPCC), Mr Hewitt previously coordinated the actions of UK police forces on matters including terrorism and organized crime.

Italy has recently seen a dramatic drop in the number of migrants making the dangerous crossing from North Africa.
Reducing the number of people crossing the Channel from France in small boats is one of the major challenges facing the new Labor government.

The Border Security Command will bring together intelligence agencies, police and Border Force personnel to tackle smuggling gangs behind small boat passages.
Mr Hewitt led the NPCC between 2019 and 2023 and previously served as Assistant Commissioner in the Metropolitan Police.
Downing Street said his experience of coordinating the work of police, government and other agencies, including responding to major security threats and managing the UK's response to the Covid pandemic, was “key to his appointment”.
Prime Minister Sir Keir Starmer said: “There will be no more tricks. This Government will tackle the trafficking gangs that trade the lives of men, women and children across borders.
“Martin Hewitt's unique expertise will lead a new era of international enforcement to dismantle these networks, protect our coasts and set up the refuge system.”
Mr Hewitt said: “I am under no illusions about the challenges that lie ahead, but I am determined to meet them.

After winning power, Labor scrapped the previous Conservative government's plans to send some asylum seekers from the UK to Rwanda.
Under the Italian agreement, migrants will be able to apply for asylum in Italy while still living in Albania. If refused, they face deportation.
This differs from the now abandoned Rwanda scheme, where asylum seekers were not allowed to return to the UK if their claim was accepted and were instead able to stay in Rwanda.
A Conservative Party spokesman said: “Ker Starmer has absolutely no plans to stop the boats, and that is why he is now trying to copy others.”
He said Labor had “destroyed this country's crackdown on illegal immigration and signaled to rogue people-smuggling gangs that they are unwilling to take the serious action needed to stop the boats”. .
Frontex, the EU's border force, has calculated a 64 percent drop in people crossing from North Africa to Italy this year.
Central to the decline of crossings in Italy are financial deals with Tunisia and Libya – where most people leave for Europe.
The EU has given Tunisia financial aid to boost border security, while Italy has provided patrol boats and given the government money to support small companies and invest in education and renewable energy.
Italian Prime Minister Meloni, who leads Italy's right-wing coalition, was a close ally of Sir Kiir's conservative predecessor, Rishi Singh.
