Chief executives of charities, voluntary organisations and social enterprises are being invited to vote in Britain's Most Admired Charities, an annual set of four awards run by Third Sector.
Those who vote will also be invited to a champagne reception and awards ceremony staged by Barclays, the hosts of the awards, on the 30th floor of its headquarters in London's Canary Wharf on the evening of Tuesday 18 October.
The four categories in the awards are Most Admired Charity, Most Admired Chief Executive, Most Innovative Charity, and Celebrity Charity Champion.
Last year's winners were the food poverty charity FareShare, James Partridge of the disfigurement charity Changing Faces, the offender rehabilitation charity the St Giles Trust and the actor Joanna Lumley.
Candidates for this year's awards were nominated by a panel of 10 sector experts and shortlists of six in each category were drawn up by Third Sector staff.
BMAC, which started in 2003, is different from other charity awards in that the winners are chosen by sector chief executives rather than by a panel of judges.
The awards night, televised on Channel 5 last year, is a key networking event at a spectacular venue. For comments from those who attended last year, click here.
The deadline for voting is Monday 22 August.
