for not understanding the importance of school architecture and accused of having misrepresented the cost. In February 2011, he had told Parliament that one individual had made £1,000,000 in one year when the true figure was £700,000 for five advisers at different times over a four-year period. During the Cameron–Clegg ministry, Gove was the subject of repeated criticism for alleged attempts to avoid the provisions of the Freedom of Information Act. The criticism surrounded Gove's use of various private email accounts to send emails that allegedly related to his departmental responsibilities.
