Jonathan to broker peace in zanzibar

I think there may be some confusion here!

Jonathan is a common given name, but I'm not aware of any specific individual named Jonathan who is a renowned broker of peace in Zanzibar or anywhere else.

Zanzibar is a semi-autonomous region of Tanzania, and while it has a complex history of conflicts and power struggles, I'm not aware of any recent or ongoing peace-brokering efforts led by a person named Jonathan.

If you could provide more context or clarify which Jonathan you are referring to, I'd be happy to try and help you better!
