The Ambassador of the United Kingdom to Greece is the United Kingdom's foremost diplomatic representative in Greece, and head of the UK's diplomatic mission in Greece. The official title is His Britannic Majesty's Ambassador to the Hellenic Republic. The modern Greek state (then the Kingdom of Greece) was established in 1832 at the London Conference of 1832 and internationally recognised in the same year by the Treaty of Constantinople, in which Greece secured full independence from the Ottoman Empire. Besides the embassy in Athens, the UK government is represented by vice-consulates on the islands of Corfu, Crete and Rhodes, and by an honorary vice consulate on Zakynthos.
