The way in which men only freemasonic groups impact upon diversity within the City of London Corporation is disturbing. To date there have been 688 Lord Mayors who were men and 2 who were women. Since the founding of the Guildhall Lodge in 1905, 78 Lord Mayors of London have belonged to this men only freemasonic group. So over the past 113 years at least 69.03% of Lord Mayors of London have been masons, whereas 1.77% have been women. Although well under 1% of the English population are masons, members of the brotherhood have a better chance of becoming Lord Mayor of London than non-masons; and women who aren’t allowed to join influential all male lodges are largely excluded from such leadership roles.
