Ramsden voiced hope the decision would further improve Croatian-British cooperation in many areas.
British Home Secretary Charles Clarke today informed the British parliament of the decision, three weeks before the abolishment goes into force, which is standard procedure, said Ramsden.
He added Croatians travelling to Great Britain would have to obtain a visa if their sojourn exceeded six months.
Croatian citizens will still have to go through immigration control, as do all citizens whose countries are not European Union members, and if they intend to work in Great Britain they will have to obtain a work permit, the ambassador said.
Great Britain introduced visa requirements for Croatian citizens on 19 November 1999 following a high number of asylum applications. Visas were also required for transit through British airports, although in October 2003 London revoked the decision on visa requirements for direct transit.
Ramsden said that about 15,000 Croatian citizens applied for a British visa annually.
Prime Minister Sanader said Britain's latest decision was a result of the Croatian government's policy. He informed parliament of the decision during today's Question Time.
