Proposals from Labour to tighten asylum laws were branded 'tinkering at the edges' on Wednesday night.
Refugees will lose the automatic right to settle in Britain for life, under plans to be set out on Thursday.
Current rules which mean most granted asylum are automatically entitled to apply for 'indefinite leave to remain' after five years are to be ended.
In addition, refugees' rights to bring relatives here are unlikely to be restored after they were temporarily halted this summer.
Downing Street said the changes, to be announced by Sir Keir Starmer at the European Political Community summit in Copenhagen, will reduce the 'pull factors' drawing migrants across the Channel.
