Gay rights activists from Commonwealth countries are demanding that laws banning homosexuality should be overturned.
Campaigner Peter Tatchell has said people face violence and imprisonment just because they are gay.
The British Foreign Secretary, Boris Johnson, promised the Olympic diver Tom Daley that he would raise the issue at the Commonwealth summit.
So, where is homosexuality still outlawed?
There are 53 countries in the Commonwealth and most of them are former British colonies.
