His first UK art exhibition, also called Pursued by Bishops, is at the Parish Church of Saints Peter & Paul in Tonbridge, Kent.

An exhibition called Sylvette: Picasso and The Model is showing at the Kunsthalle Bremen museum in Germany next year and the Francis Kyle Gallery is holding an exhibition of Lydia's own work early in 2014.
