OXFORD University Press (OUP) has changed its geography textbook for teenagers after it sparked a row with the Ukrainian Government.

The latest edition of Geog.3 – aimed at pupils aged 11 to 14 – now says Crimea is part of Ukraine but is controlled by Russia.

It has been on sale since February 29.

The Walton Street publisher was criticised by one of Ukraine’s top diplomats last October for saying Crimea was a Russian "exclave".

The Ukranian embassy in London demanded the book be changed and said this morning that it welcomed the "correction".

The Crimean Peninsula was annexed from Ukraine in 2014 by Russia, after a revolution in Ukraine and the ousting of its former pro-Moscow president Viktor Yanukovych.

Its annexation followed a referendum held by pro-Russian forces, which was branded illegal by Britain and its allies.

A spokesman for OUP confirmed it would accept old textbooks in exchange for copies of the new one from anybody who wished to swap.

He added: "The updated version explains the situation in Crimea in more detail, providing more details about the events of 2014 and the reaction of the international community.

"All of our atlases and geographic resources are developed through detailed research into the political, social, and economic situation at the time of publication.

"We continuously review all of our materials to reflect changes in circumstances and feedback from various sources and would like to thank our customers for bringing this to our attention."
