Pity those poor long-suffering secretaries and researchers of LibDem ministers. Bag-carriers working for Danny Alexander, Jeremy Browne and Lynne Featherstone have been sent on a course specialising in “dealing with challenging behaviour” over the last few months. Overall MPs have spent more than £10,000 on sending their staffers on the programme, all at the expense of the taxpayer. None of Gordon’s staff are on the list, but then they could probably teach the course.
