Benedict XVI lived away from the Vatican for a while after his resignation, giving Francis time to get himself established. Then Benedict moved to an apartment in the Vatican, which was probably good for financial and security reasons.

I've read that Francis consults with Benedict quite often. Benedict spends his time writing and studying, which is what he's good at (even Donuel might like his writing). The arrangement seems to be working very well.

Yes, there are Catholics who do not see the resignation of Benedict and the election of Francis as legitimate. Heck, the Sedevacantists believe that the election of John XXIII in 1958 was not legitimate, and that the Chair of Peter has been vacant since 1958 (sedevacantist="empty seat").

There have been antipopes thoughout the history of the Catholic Church, especially during the 14th century. There were three popes at one period of time then, each with well-known saints supporting them. I suppose the plethora of antipopes in the 14th century was the result of moving the papacy to Avignon in France. That move didn't sit well with a lot of people.

Can't say I put any credence in the catty-toned article from Cornwell, who seems to have a very destructive agenda.
