A senior UK Government minister has been branded "disrespectful" over his failure to address a Holyrood committee on welfare reform.
Michael McMahon, the convener of the Scottish Parliament's Welfare Reform Committee, said they had urged Work and Pensions Secretary Iain Duncan Smith to appear before them no fewer than five times now.
In November, the Labour MSP had said it was "beyond disappointing" that Mr Duncan Smith had "refused to give public evidence to our committee".
He has hit out at the Tory politician again, claiming the UK Government minister was prepared to speak on the issue at a conference in Scotland, but would not come to Holyrood.
Mr McMahon said it was "particularly galling to find out that the Secretary of State for Work and Pensions, the Rt Hon Iain Duncan Smith MP, is to address a conference on the subject of welfare reform in Scotland".
