Barcelona: A far-right party has taken a role in the formation of a regional government in Spain for the first time since the Franco dictatorship ended in 1975.

The anti-immigrant Vox on Wednesday agreed to support a centre-right coalition in Andalusia. It became kingmaker in Spain's most populous region - a traditional Socialist Party stronghold - after 12 of its candidates unexpectedly won seats in an election in December.

While Vox will not be part of the Andalusia government, bitter memories of military dictatorship had until now prevented far-right parties from making any inroads into the Spanish political mainstream.

Francisco Franco died in 1975 and democracy was re-established three years later.
