Landmark ruling at Coventry meeting.
The decision will allow a wide range of new charitable organisations to join.
Members of the NAVCA, the National Association for Voluntary and Community Action, have supported a proposal from the trustees to invite a wide range of local voluntary and community sector (VCS) infrastructure organisations to join the body.
The motion, at the charity's AGM in Coventry, achieved 97 per cent support. A similar proposal one year ago was voted down by the members.
NAVCA began life in 1991 as the NACVS, a national voice for Councils for Voluntary Service (CVS). The change means that other types of local infrastructure organisations will be able to join including Learning and Skills Consortia, Community Empowerment Networks and Black and Minority Ethnic infrastructure.
