An audio tape of a private speech by Hungarian Prime Minister Ferenc Gyurcsány is leaked to the public, in which he confessed that his Hungarian Socialist Party had lied to win the 2006 election, sparking widespread protests across the country.

The Őszöd speech was a speech Hungarian Prime Minister Ferenc Gyurcsány delivered to the 2006 Hungarian Socialist Party (MSZP) congress in Balatonőszöd. Though the May congress was confidential, Gyurcsány's address was leaked and broadcast by Magyar Rádió on Sunday, 17 September 2006, igniting a nationwide political crisis.

The 2006 protests in Hungary were a series of anti-government protests triggered by the release of Hungarian Prime Minister Ferenc Gyurcsány's leaked private speech in which he confessed that his Hungarian Socialist Party had lied to win the 2006 election, and had done nothing worth mentioning in the previous four years of governing. Most of the events took place in Budapest and other major cities between 17 September and 23 October. It was the first sustained protest in Hungary since 1989.
