The chairman of the Conservative party Grant Schapps has asked the UN Secretary General to look into why one of his rapporteurs made disparaging remarks about the so-called bedroom tax months before a report on the controversial policy was due.
In a letter to Ban Ki-Moon, Mr Schapps accuses Raquel Rolnik of showing "political bias" on a fact-finding mission to the UK:
I believe that the Special Rapporteur's report has been influenced by political bias and suggest that the UN withdraw her claims pendign a full investigation.
Ms. Rolnik's investigation lasted for less than 12 days. In the course of this investigation, not once did Ms. Rolnik request a meeting with the Secretary of State at the Department for Work and Pensions, nor anyone within the Department ... nor did she request any detailed policy analysis from the Department.
He also accuses her of taking part in a photo opportunity with a Scottish newspaper, the Daily Record, which has "actively campaigned" against the policy.
