Cabinet office policy applies to foreigners coming to the department to take part in ‘learning and development’ events. Managers are urged to carefully check the background of such visitors, including looking for positions up to five years old, according to a Financial Times article.

He added: “Instead of seeking to silence perfectly legitimate criticism of their litany of failures, ministers could do with listening to the experts a little more and burying their heads in the sand a little less. By listening they might learn something about dealing with the dysfunction that has built up at the heart of this Conservative government.” The Cabinet Office said speakers would not be automatically banned if they had previously posted comments critical of the government and would be considered on a case-by-case basis.
