The hearing followed an investigation by The Standards Board for England into an allegation that Mr Smith had breached the councillors' code of conduct by making indecent photographs of a child under the age of 16. The panel agreed with the finding by the Board's ethical standards officer that, by his actions, Mr Smith had brought his office and his authorities into disrepute.
Anthony Holland, chair of The Standards Board for England, said:
'We welcome this decision by the panel. The public should have confidence that members live up to the high standards expected of them. Those who fall short and tarnish the good work done by the vast majority of members must be brought to account.'
Mr Smith resigned from both authorities on 9 February 2004.
The Standards Board for England is responsible for promoting high ethical standards and investigating allegations that members' behaviour may have fallen short of the required standards.
The Adjudication Panel for England, which is an independent body, holds hearings to reach determination and imposes sanctions on local authority members who have been subject to investigation by The Standards Board for England.
