Please answer a question about the following article about John, King of England:

John was incensed about what he perceived as an abrogation of his customary right as monarch to influence the election. He complained both about the choice of Langton as an individual, as John felt he was overly influenced by the Capetian court in Paris, and about the process as a whole. He barred Langton from entering England and seized the lands of the archbishopric and other papal possessions. Innocent set a commission in place to try to convince John to change his mind, but to no avail. Innocent then placed an interdict on England in March 1208, prohibiting clergy from conducting religious services, with the exception of baptisms for the young, and confessions and absolutions for the dying.

Who was barred Langton from entering England?
