The Rainbow Group in the European Parliament was a regionalist political group with representation in the European Parliament between 1989 and 1994.
In 1989 the previous Rainbow Group split. The Greens formed The Green Group in the European Parliament, whilst the Regionalists stayed in the remaining Rainbow Group.
This second Rainbow Group was the highpoint of the European Free Alliance (EFA) to that date.
But the 1994 elections saw a considerable reduction in Regionalist representation in the Parliament, with only the Canarian Coalition, Lega Nord, Scottish National Party and People's Union keeping their MEPs. But Lega Nord had been suspended from the EFA following its decision to join the Italian coalition government alongside the right-wing National Alliance. The weakened EFA was no longer able to maintain their own group, and instead allied themselves with the members of the French Energie Radicale to form the Group of the European Radical Alliance.
