What female world leaders have attended Oxford University?

Pinpointing *all* female world leaders who attended Oxford is difficult due to varying definitions of "world leader" and the lack of a central, comprehensive database. However, some notable examples include:

* Indira Gandhi (India): While she didn't complete a degree, she studied at Somerville College, Oxford.

It's important to note that many other women who *later* became prominent in politics may have attended Oxford, but weren't necessarily "world leaders" at the time of their attendance. Finding a complete list requires extensive research across many countries and political systems.
