The global evidence is clear: active intervention is needed for male female parity in power.

The record high of 191 women MPs – 29 per cent – elected to the House of Commons on 7 May was an increase of 48 women from the immediate post-2010 election results.

An improvement, clearly.

But the number of women elected to Westminster remains a long way from parity; and the 2015 election results put the UK in only 37th place worldwide in terms of women with parliamentary seats.
