Unemployed youngsters will have to agree to learn key skills if they want to have access to any sort of benefits, Ed Miliband is expected to say.
The Labour leader wants 18 to 21-year-olds to sign on for a "youth allowance" instead of jobseeker's on the condition they learn key skills which will get them into work.
Out-of-work youngsters who have well off parents will not be entitled to any unemployment benefit, the Labour leader will say.
People will also have to work longer to qualify for a boosted rate of jobseeker's allowance, as part of moves to restore the contributory principle to the system.
The commitments, unveiled in a speech to the IPPR think-tank, come with Mr Miliband facing persistent questions about his leadership with under a year to go until the general election.
