The number of women leading local authorities in England has risen to 48 - an increase or just one on the 2014/15 municipal year.
Interim findings from the Centre for Women & Democracy's research on women in local leadership roles (to be published in the autumn) also show that:
Commenting on the findings CFWD's Director, Nan Sloane, said: 'It's disappointing to find that there is virtually no progress in improving women's representation at this key level of democracy. Not only does it have implications at local level, but it will also impact on the new devolution arrangements - very few women will be in the room when the decisions are made, and we already know that women are less likely to be elected to roles such as Executive Mayor or Police & Crime Commissioner. All the parties need to think urgently about what they're going to do about this.'
Elsewhere in Europe women have been making high-profile gains recently; Paris, Barcelona and Madrid have all elected women mayors.
