The Labour Party's electoral victory means that Joseph Muscat, 39 becomes Malta's second youngest ever prime minister, and the youngest since Dom Mintoff was first elected in 1955.
The youngest ever prime minister was Sir Ugo Mifsud, co-leader of the Nationalist Party, who was 35 when he first became prime minister in 1924.
This was the first time that Joseph Muscat was a general election candidate, but in 2004 he became the first Labour candidate to be elected to the European Parliament, and he served there until 2008, when he was elected to succeed Alfred Sant at the helm of the Labour Party.
Married to Michelle and with two young twin daughters, Dr Muscat was educated at St Aloysius College and was a a Super One journalist and a financial adviser before taking his seat in the European Parliament.
As PL leader, he moved the party to the centre, opening it up to sectors which previously tended to support the Nationalist Party. His extensive reform even included changing the party's formal name and emblem.
