Margaret Thatcher: Yvette Cooper? Theresa May? When Will Britain Get Another Female Prime Minister?

Britain will not get another female Prime Minister until at least 2020, more than 40 years after Margaret Thatcher was elected, according to bookmakers.

Betting agent William Hill has odds of 1/2 that another female Prime Minister will not be in office until after two more general elections, with long odds of 20/1 that a woman will be in Number 10 in 2015.

The bookmaker is also offering odds of 6/4 that a female leader will emerge in the years 2016 to 2019.

Could Labour's Yvette Cooper be the next female PM?

It is deputy Leader of the Labour Party, Harriet Harman and Shadow Home Secretary Yvette Cooper, along with current Home Secretary Theresa May, who are favourites to be the next woman to follow in the footsteps of Thatcher.

But two women, Cooper and May, are favourites to be the next leaders of their respective parties, beating all their male colleagues.

Cooper, who is married to Shadow Chancellor Ed Balls, is 12/1 to be the next Prime Minister, according to William Hill, and May is 20/1.

There are currently 17 female world leaders in office, from Iceland to Liberia to Bangladesh, including German Chancellor Angela Merkel and Australian Prime Minister Julia Gillard.

Although opposite in her political ideology, Gillard paid tribute to Thatcher this week for paving the way for female prime ministers. "Her service as the first female prime minister of the United Kingdom was a history-making achievement," she said in a statement.
