Mahmood will use the speech to step up her attacks on the Greens, accusing the party of wanting to create “a world without borders” and calling for “the most expensive and expansive migration policies anywhere in the world”.
On its website, the Green Party says, external in government it would “treat all migrants as if they are citizens” and “dismantle the Home Office”.
A Green spokesperson said the home secretary was “deliberately misrepresenting Green Party Policy and reducing it to cheap soundbites”.
The Green Party said it recognised “the great contribution that migrants and refugees make to British society and we want to see policy that treats everyone with dignity rather than treating them harshly for political gain”.
Chris Philp MP, shadow home secretary, said Labour “should put foreign criminals on a plane home, not onto British streets”.
The Refugee Council, a charity, has warned that the plans could lead to an uptick in rough sleeping, shifting costs to local councils and the NHS.
Imran Hussain, its director of external affairs, said speeding up slow decision-making was a “far more effective” way to reduce costs.
Just over 107,003 people in the UK were receiving taxpayer-funded asylum support at the end of last year, including around 30,000 in hotels.
The government has pledged to phase out the use of hotels by 2029, and plans to move people to lower-cost large sites including former military bases.
