Germany will tighten its law to make it easier to prosecute those helping to smuggle migrants to the UK, as part of a new plan agreed between the two countries.
Facilitating people-smuggling is not technically illegal in Germany currently, if it is to a third country outside the EU - which, following Brexit, includes the UK.
Under the new agreement, the Home Office says Germany has pledged to make the activity a clear criminal offence.
Home Secretary Yvette Cooper said the "ground-breaking" agreement would help tackle the criminal gangs organising small boat crossings.
The Conservatives said the plan did not "go far enough" and would not provide the deterrent necessary to reduce crossings.
