His own was the most recent of the private consecrations and before that Ballini in Ireland and Stobnicki in Poland. Even though it was early last year, it remained secret but gradually leaked out until it was officially declared by Bishop Williamson in the above sermon. He is now visiting places for the first time as a bishop which is the reason these matters are coming to the fore.
OK, so the OP was about his own consecration. That's what I thought. I had NO IDEA it took nearly
2 years for an official announcement.
