On 15 August 2011, Swedish Prime MinisterFredrik Reinfeldt officially apologized to the prime ministers of Estonia, Latvia and Lithuania in a ceremony in Stockholm saying that "Sweden owes its Baltic neighbours a "debt of honour" for turning a blind eye to post-war Soviet occupation" and speaking of "a dark moment" in his country's history.[1] Sweden re-recognized Lithuania's independence on August 27, 1991.
