He became MP for Cardiff West in the Conservative landslide of 1983. As in other constituencies, his
Labour Party opponent suffered a loss of votes to the breakaway
Social Democratic Party. In Parliament, Terlezki remained true to his right-wing reputation, introducing a bill to replace the
May Day holiday with a day of celebration for
Winston Churchill. However, he mostly concentrated on constituency work and secured an increase in his vote at the 1987 election (although a lower percentage). However, through the collapse in support for the Social Democrats, he lost his seat to Labour's
Rhodri Morgan. At
Westminster, Terlezki also had the chance to do something about his father's plight. He persuaded the Foreign Secretary,
Sir Geoffrey Howe, to raise the case with his Soviet counterpart,
Andrei Gromyko. As a result, in October 1984, his father was flown to London for a monthlong reunion and subsequently allowed to return to Antonivka, where he died in 1986. Terlezki requested a visa to attend the funeral but it was not issued in time. However, he and his Welsh wife, Mary, together with their two daughters, later visited his home village as guests of the Soviet authorities. ==End of Communism==
