On final day of campaign, Erdogan accuses Turkish opposition of working with Biden

ISTANBUL (Reuters) -Turkish President Tayyip Erdogan held his last election rallies in Istanbul on Saturday, accusing the opposition of working with U.S. President Joe Biden to topple him while making a final appeal ahead of the biggest challenge to his 20-year rule. Voters will also elect a new parliament, likely a tight race between the People's Alliance comprising Erdogan's conservative Islamist-rooted AK Party (AKP) and the nationalist MHP and others, and Kilicdaroglu's Nation Alliance formed of six opposition parties, including his secularist Republican People's Party (CHP), established by Turkey's founder Mustafa Kemal Ataturk.
