In Italy, Mr Salvini's League, an anti-immigrant party, claimed nearly 34% of the vote in early projections - a jump from around 6% five years ago.
Mr Salvini said: "Not only is the League the first party in Italy, but Marine Le Pen is first in France, Nigel Farage is first in Great Britain.
"Therefore, Italy, France and England: the sign of a Europe that is changing, that is fed up."

Current MEPs' terms end on 1 July, with the new parliament being seated the next day.
