The admin of the Bishop Williamson (unofficial) Telegram has posted this:
I had the honour of visiting Bishop Williamson today in the QEQM hospital today. The doctors estimate he is most likely to die within the next 24 hours, and even if he recovered, he would be in a vegetative state. We prayed the rosary around him, he again received extreme unction and mass was said in his room, both of which I had the privilege of participating in. Bishop Richard Nelson Williamson would and does want us to pray the rosary for him, so please do.
God bless you all
