A row has broken out over another delay in the transfer of disability benefits to Holyrood.
An extension means the UK-wide DWP could end up delivering the disability living allowance and other payments for an extra three years until 2026.
Labour MSP Pam Duncan-Glancy said: "The relationship between Scotland's two governments has descended into chaos once again, leaving the SNP's promise to deliver a fairer, functioning Scottish social security system in tatters. Every day that this programme is delayed is another day that disabled people and carers are left at the mercy of a Tory-run DWP".
