<human>:  Why did the Irish government collapse?
<bot>: The Irish government collapsed in 2021 because the Fianna Fáil party lost the election. The Fianna Fáil party was the largest party in the country for many years, but it lost the election to Sinn Féin, a left-wing party that had been banned from participating in elections for many years. The new government is currently led by Leo Varadkar, who is the current Taoiseach, or prime minister.
