From the Tablet website:
At least 20 clergy and around 600 laity are to leave the Church of England to prepare to join the newly established ordinariate. Priests and people need to formally decide to join the new structure by Ash Wednesday, which is next week, in order to be part of the first wave of converts. They will leave their places of worship and attend Catholic churches in preparation for being received into the Church during Holy Week. The largest numbers of people announcing their intention to join come from the southeast of the country.
