Andrew Bazeley, policy and insight manager at the Fawcett Society, which campaigns for gender equality and women's rights, said: “This data is concerning and clearly demonstrates that more needs to be done to support women to get into and, crucially, stay in politics.
"We don't just need to see flexibility introduced to support those with caring responsibilities. We need to see sexism stamped out and misogyny consigned to the history books. Women must be supported across the political spectrum to play a bigger part in our democracy."
