The ECHR puts the rights of British citizens 'beneath those of criminals', Reform UK's pick for home secretary has said.
Zia Yusuf said his party would withdraw from the European Convention on Human Rights (ECHR) to stop the rights of foreign criminals being 'prioritised' over British people.
In his first speech since being appointed home affairs spokesman, he set out plans to tackle what he branded an 'invasion' of illegal migrants and deport 288,000 every year.
He said the party would leave the ECHR as he cited the case of an Iraqi asylum seeker who killed a British girl but was allowed to remain in the UK by British judges.
'How many more people must die at the hands of those who should never have been in our country in the first place?' he said.
'How many more victims' families must be devastated in this way when their rights are placed beneath those of criminals?'
The party also announced a new policy called the 'Polanski Law' after the Green Party leader who has called for small boat migrants to be allowed to live and work in the UK.

Zack Polanski has visited camps in Calais and urged the UK Government to spend £500 million to help migrants there.
Reform said its new law would make encouraging or assisting anyone to illegally enter the UK a criminal offence punishable by up to two years in prison, regardless of their intention.
Elsewhere in the press conference, Mr Yusuf said that he backed a ban on 'all face coverings in public' after he was asked whether he supported a burqa ban.
Last year, Mr Yusuf, a practising Muslim, briefly quit the party after he described a question to the Prime Minister about a ban on burqas as 'dumb'.
He told the press conference: 'I personally support a ban on all face coverings in public… that's actually a piece of legislation that has multiple bonuses to it because it's going to aid integration, it's also going to help people feel safe.'
It came after the party's new education and equalities spokesman, former Tory minister Suella Braverman, renewed her call for a burqa ban.
Speaking in Dover - the town most associated with the small boats crisis - Mr Yusuf set out his plans to deport all illegal migrants in the UK.
Describing it as an invasion, he said: 'I know many in the establishment gasp at that word.
'They may well clutch their pearls in the television studios, but the dictionary definition of invasion is an incursion by a large number of people in an unwanted way.'
He added that the party expected to deport more than 600,000 in its first term in government. There would be five deportation flights a day, he added.
Mr Yusuf said he would impose 'visa freezes' on Pakistan, Afghanistan and Syria if they refuse to take back migrants the UK turns away.
He also pledged to create a new 'UK Deportation Command' - a British version of Donald Trump's America's controversial US Immigration and Customs Enforcement (ICE) unit.
He said the unit would 'track down, detain and deport' people in the country illegally.
He said it was 'not true' that the UK version would face the same issues as the American one after an immigration crackdown in Minnesota led to mass detentions, protests and two deaths.
Under the party's plans, the Home Secretary would be legally compelled to deport illegal migrants, foreign nationals would be stripped of benefits and stop and search would be expanded.
Other plans would include automatic home searches for anyone referred to the Prevent anti-terrorism strategy.
Listed status would be given to all churches to prevent them being turned into mosques to protect the UK's Christian heritage, Mr Yusuf added.
Shadow home secretary Chris Phlip said Mr Yusuf has 'nothing new to offer beyond copying and pasting Conservative plans'.
Labour Party chair Anna Turley said: 'Britain is a proud, tolerant and diverse nation, which stands in opposition to the kind of divisive politics stoked by Reform.'
