Reform has pledged to impose tariffs on countries that refuse to accept the return of migrants who have entered the UK illegally, as part of a package of measures aimed at stopping Channel crossings.
The party is also proposing bans on foreign airlines using British airspace and restrictions on visas for nationals of countries that decline to take back deportees.
Nigel Farage said the measures would extend Reform’s existing plans for “visa freezes” affecting people seeking to visit the UK legally from countries including Pakistan, Afghanistan and Syria.
The proposed visa restrictions would also apply to nationals of Eritrea, Sudan and Somalia. Reform said tariffs would provide an additional option against countries less affected by visa bans, with Egypt cited as a potential example.
Further details of the proposals are expected to be published this week.
Mr Farage said: “I will not tolerate countries who won’t take back illegal migrants.
“I’ll impose tariffs, airline bans and visa bans on any country that refuses.
“Only Reform will end the invasion of our country forever.”
Reform’s plans for deportations
The party also intends to negotiate agreements with third countries to deport people in what it describes as “extreme cases”, where their country of origin is unwilling to accept them or returning them there would be inappropriate.
In addition, Reform would review every refugee status decision granted during the five years before a Reform government took office.
