English Football League clubs have been urged to sign up to the Football Association's Leadership Diversity Code, after it emerged only 27 of the 72 sides have pledged their support and only four in League Two.
The code, which was launched in October, is aimed at increasing diversity and inclusion throughout English football.
It immediately attracted the support of 40 clubs across the Premier League, English Football League, Barclays FA Women's Super League and FA Women's Championship.
Nineteen of the 20 Premier League clubs pledged their commitment, but Southampton chose not to sign up initially, because they had just achieved the Premier League's Advanced Equality Standard and they continue to consider how the FA's code will complement this work.
