The Charity Commission is to launch a campaign in August to encourage more young people and those from ethnic minorities to become charity trustees.
The commission will join forces with volunteering charity TimeBank and other potential partners for the campaign. It will be the first time that TimeBank has highlighted trustee positions in a campaign.
The initiative is a response to concerns that trustees tend to be overwhelmingly middle-aged or older, and white. Figures from the NCVO show that 71 per cent of trustees are 45 or over and 4.8 per cent are from an ethnic minority background, compared with 7.8 per cent of the total UK population.
The NCVO's figures also show that 55 per cent of trustees are men and that this proportion increases among larger organisations.
Becky Drake, senior press officer at the Charity Commission, said: "Increasing diversity is going to be a factor in the campaign. We want to target under-represented pockets of the communities and make things more open. Traditionally, recruitment has been by word of mouth."
