[2] After losing their parliamentary seats as a result of the general election, many members including the regional president Luis Javier Rodríguez Moroy were forced to stand down over compatibility issues.

[12] The General Deputation of La Rioja was the devolved, unicameral legislature of the autonomous community of La Rioja, having legislative power in regional matters as defined by the Spanish Constitution and the Riojan Statute of Autonomy, as well as the ability to vote confidence in or withdraw it from a regional president.

Voting for the General Deputation was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered in La Rioja and in full enjoyment of their political rights.

The 35 members of the General Deputation of La Rioja were elected using the D'Hondt method and a closed list proportional representation, with an electoral threshold of five percent of valid votes—which included blank ballots—being applied regionally.

The highest percentage figure in each polling survey is displayed with its background shaded in the leading party's colour.
