Former Alternattiva chairman Harry Vassallo has been appointed chairman of the Guardian of Future Generations.
He was appointed by the Prime Minister on the recommendation of Environment Minister José Herrera.
The role has been vacant since June, when the previous Guardian, Maurice Mizzi, quit under a cloud.
