Ministers and officials to be banned from contact with groups labelled extremist

New extremism definition to be published by Michael Gove is already being challenged by Muslim groups and experts

Ministers and civil servants will be banned from talking to or funding organisations that undermine the UK's system of liberal parliamentary democracy", under a new definition of extremism criticised by the government's terror watchdog and Muslim community groups.

Michael Gove, the communities secretary, will tell MPs on Thursday that officials should consider whether a group maintains public confidence in government" before working with it.
