In his position in the Ecumenical Patriarchate's Exarchate in Western Europe, Bishop Basil's authority is over a newly-formed vicariate of parishes in the British Isles entitled the Episcopal Vicariate in Great Britain and Ireland, which currently consists of a small number of parishes and some smaller Eucharistic Communities that elected to follow him in his departure from the Diocese of Sourozh (these are enumerated and discussed here). As part of this role, he sits on the council of the Exarchate.
