BBC's coverage of the Platinum Jubilee has come under fire after the Irish tricolour made an unexpected appearance during a concert held outside Buckingham Palace.
The UK's national broadcaster has issued an apology after the Irish flag was displayed to represent Ulster.
The green, white and orange tricolour was used when comedian Doc Brown spoke about being "proud to be British". However, this received huge backlash online as Ireland has not been a part of the United Kingdom since 1937 and became a republic in 1949.
