UK-Europe and Africa Diocese is one of the 30 dioceses of the Malankara Orthodox Syrian Church. In accordance with the geographical division implemented in 2009, the Diocese of UK-Europe and Africa was established with the purpose of encompassing all parishes, congregations, and spiritual organizations of the Malankara (Indian) Orthodox Syrian Church within the boundaries of Europe and Africa.

L.L His Holiness Moran Mar Baselios Marthoma Paulose II, the then Supreme Head Malankara Metropolitan and Catholicos of the East, appointed His Grace Dr. Mathews Mar Thimothios as the inaugural Diocesan Metropolitan of this newly instituted diocese, a position he assumed in May 2009. Prior to this significant development, these parishes were subject to the jurisdiction of LL Thomas Mar Makarios, the former Diocesan Bishop overseeing Canada, UK, and Europe.

Following His Holiness Baselios Marthoma Marthoma Mathews III’s Kalpana (No 344/2022), His Grace Dr. Mathews Mar Thimothios was relieved of the responsibilities as Diocesan Metropolitan and His Grace Abraham Mar Stephanos succeeded him by assuming office as the Diocesan Metropolitan of the UK-Europe and Africa Diocese in November 2022.
