Female heads of state

Now, since Angela Merkel became chancellor of Germany, there are currently 10 countries in the world whose governments are led by women. Here is a list:

1. Bangladesh (Begum Khaleda Zia)
2. Finland (Tarja Halonen)
3. Germany (Angela Merkel)
4. Ireland (Mary McAleese)
5. Lettland (Vaira Vike-Freiberga)
6. Liberia (Ellen Johnson Sirleaf)
7. Mozambic (Luisa Dias Diogo)
8. New Zeeland (Helen Clark)
9. Phillipines (Gloria Arroyo)
10. Sao Tome and Principe (Maria do Carmo Silveira)

I do not know if these female presidents, chancellors, prime ministers do so much for the women in the world, but anyway there should be more of them.
