A former chairman of governors has launched an appeal to overturn a ban imposed on him over an alleged "Trojan Horse" Muslim takeover plot in schools.
Tahir Alam was banned from involvement in schools by the Department for Education (DfE) in September 2015.
Officials ruled he had engaged in conduct aimed at undermining fundamental British values.
Mr Alam, the former head of governors for Park View Education Trust, has always denied any wrongdoing.
A specialist tribunal began analysing appeal evidence on Wednesday.
