The BBC has seen documents, commissioned by Conservative officials, examining the options for billions of pounds of welfare cuts if they win the election.
They include proposals to cut unemployment, sickness and disability benefits, with some claimants losing up to £80 a week.
The Conservatives told the BBC that officials studied many options and it would be wrong to suggest these were part of their plan.
