Katharine Birbalsingh, the head of the Michaela Community School in Wembley, is said to have been shortlisted for the role of chair of the government’s Social Mobility Commission (or ‘Social Mobility Tsar’). The job pays £350 a day for up to six days’ work a month. Birbalsingh delighted the Conservative Party Conference in 2010 with a speech that emphasised ‘discipline’ and ‘personal responsibility’ and included some snide remarks about grade inflation and political correctness, interspersed with clips of her students playing the steelpans. Music to the Tories’ ears.
