Zia Yusuf will today unveil sweeping proposals to stop small boat Channel crossings, destroy knife crime gangs and root out Islamist extremism as Reform UK’s new home affairs spokesman.

The party figure is expected to describe immigration as a “national security emergency” when he addresses supporters in Dover , Kent on Monday.

Both major parties have been “turning the other way while the fabric of our society has been under assault”, he will claim.

British Ice-style agency to remove 300,000 annually

Central to his vision is creating a domestic version of America’s Immigration and Customs Enforcement — the polarising US agency known as Ice.

A new UK Deportation Command would be capable of holding 24,000 illegal migrants at any one time while processing removals of nearly 300,000 people every year.

Former military installations would serve as temporary detention centres before deportation flights leave the country. The party estimates these converted bases could be operational for 24,000 detainees within a year and a half, requiring £2.5 billion investment.

Daily deportation flights would reach five under the proposals.

Mr Yusuf said: “As a result of our mass deportation programme, a Reform government will deliver net negative immigration.”

Indefinite Leave to Remain scrapped

According to The Sun, further measures on the table include scrapping Indefinite Leave to Remain status entirely, cutting off welfare benefits for foreign nationals and freezing visa issuance to countries that won’t accept their own citizens back.

Tackling extremism would see the Muslim Brotherhood outlawed and the Prevent counter-terror scheme overhauled to address “real threats.”

Mr Yusuf will commit to “protect Britain’s Christian heritage” and block the conversion of churches into mosques.

Turning to law enforcement, he will insist police must stop producing TikTok content and driving Pride-emblazoned cars, focusing instead on arresting offenders.

Stronger stop and search legislation combined with intensive neighbourhood patrols would form the response to Britain’s knife crime epidemic.

He will also announce prison construction on an unprecedented scale — building new facilities at the “fastest rate of our lifetimes.”

Three nations face visa freeze threat

Countries including Pakistan, Afghanistan and Syria would face British visa bans unless they cooperate with deportation requests, The Times has reported.

Shabana Mahmood threatened similar action against Angola, Namibia and the Democratic Republic of Congo in November as part of Labour’s drive against illegal migration — warning those governments the UK would deny entry to their nationals without better cooperation on returns.

Culture wars and extremism dominate agenda

All three have now come to the table, but Yusuf will accuse Labour of threatening visa bans on only a “handful of African countries responsible for only a minuscule proportion of illegal migrants”.

Nations with significantly higher illegal migrant numbers — Pakistan, Somalia, Eritrea, Syria, Afghanistan and Sudan — would become Reform’s targets instead, he will argue.

Official statistics show Pakistani nationals feature prominently among visa overstayers.

Before his speech, Yusuf said on Saturday: “As home secretary I will use every instrument of state to deport all illegal migrants in Britain, including visa bans on countries that refuse to take back their illegals.

“Further countries will be announced soon. Reform will do what it takes to finally secure our borders, uphold the rule of law and put the British people first.”

Today’s speech will introduce additional policies covering what Reform frames as “protecting British culture” while adopting a “zero-tolerance” position on Islamist extremism — building on the party’s recent pledge to ban the Muslim Brotherhood.

Labour yesterday said Britain was a “proud, tolerant and diverse nation” which stood in opposition to the “divisive politics stoked by Reform.”
