The Commonwealth flag will fly at County Hall to mark the international celebration of Commonwealth Day.
County Councillor Kevin Ellard, Chairman of Lancashire County Council, will join the rest of the country by raising the flag on Monday 9 March at 10am.
Over 650 flags will be raised in 38 Commonwealth countries, including New Zealand, Jamaica and Mauritius.
Councillor Ellard will read a specially written message from Her Majesty the Queen, followed by a Commonwealth Affirmation, before the flag is raised. County Councillor Jennifer Mein, leader of the county council, will give a response to the affirmation.
Councillor Ellard said, “We are delighted to be joining together in this international celebration of the Commonwealth, its values and the opportunities it provides for people around the world.
“It provides an opportunity both to celebrate and affirm the kinship, diversity and opportunities of the Commonwealth community.
“Like the Commonwealth, Lancashire is made up of different communities. So we’re also taking a moment to celebrate the diversity of the various communities here in the county.”
