Bulgaria became a full member state of CERN on 11 June, when it gave UNESCO its instrument of ratification of the constitutive Convention of CERN.
At a ceremony during the council meeting, the Bulgarian flag was hoisted outside CERN for the first time to join the flags of the organization's 19 other member states. Bulgaria's deputy Prime Minister Vesselin Metodiev said that one of the priorities of the Bulgarian government is to develop and maintain competitive science in Bulgaria. "Our membership in CERN is an important step in this direction as it will enable many Bulgarian scientists, engineers and technical staff to work at the leading edge of science and contemporary technologies," he said.
CERN Director-General Luciano Maiani said: "Bulgaria's membership of CERN is another step forward in the unique European collaboration in fundamental physics research. We are delighted to welcome our Bulgarian colleagues to our community."
