Foreign criminals and failed asylum-seekers could be removed from Britain within 25 days under a new fast-track appeal system.
Liz Truss, the Justice Secretary, will today unveil plans to speed up deportation appeals by foreign criminals and asylum seekers who have no right to remain.
The Government believes that the scheme could speed up around 2,000 cases a year and save the taxpayer an estimated £2.7million.
Ms Truss said: "It is vital that foreign nationals who have no right to remain in the country should be removed as quickly as possible.
"We must ensure that foreign criminals and failed asylum seekers are not exploiting the justice system by attempting to stay in the UK after their claims have been rejected.
"Our proposals are also better for detainees as it will see their detention time cut."
The proposals are being introduced after ministers were forced to scrap a previous fast-track scheme following legal challenges.
In 2015 the Court of Appeal ruled that the previous scheme, under which appeals could be completed within 12 days, was unlawful because it was so quick it risked being unfair.
Since then the average time to reach a decision on an appeal has risen to 36 days, with some cases taking longer than 100 days.
The new fast-track appeals system will apply to foreign criminals at the end of their jail sentence who have been recommended for deportation.
It will also apply to asylum seekers who have been transferred to Immigration Removal centres after their claims to stay in the UK have been rejected.
Under the new scheme the time appeals at first-tier tribunals will be capped at between 25 and 28 days. A further 20 days will be allowed for further appeals that are lodged at the upper tribunal.
The independent Tribunal Procedure Committee (TPC), which sets rules for tribunals, will now consider whether and how the proposals should be implemented.
Sir Oliver Heald, a justice minister, said: "We think our proposals would provide certainty to appellants, their families and legal representatives, with a clear timetable to ensure their cases are dealt with swiftly, minimising their time in detention."
However John Pugh, a Liberal Democrat MP, said: "These proposals are too little too late. Time limits for appeals will do little to fix our shambles of an asylum system, from cash-strapped courts to lax border controls.
"The Government is simply rearranging the deck chairs on the titanic."
It came as 62 landlords were fined a total of £67,000 under a crackdown on illegal immigration.
Landlords are now required to establish that their tenants have a right to be in the country by taking copies of documents such as passports and identity cards.
Failure to comply can lead to fines of up to £3,000 a tenant, while those who knowingly rent to people with no right to be in the country can face up to five years in prison.
