Around nine o'clock of today David Cameron entered the number 10 Downing Street. Thirteen years later, the United Kingdom has again a conservative Prime Minister, but for the first time since II World War it will be a coalition Government.

Conservatives have finally made an alliance with the Liberal Democrats, who were offered several ministries and the promise of a referendum on the electoral reform. Nick Clegg will be the "number two" of the Government and the remaining names will be known during the day. The party will have four folders.

By Friday afternoon, Conservatives had become the largest party in parliament after the election for the first time in three decades. One thing is basically certain: the 13 years of power of the Labour party are over.

From the 650 parliamentary constituencies, the Conservatives had won 306 seats, followed by Labour on 258 and the Lib Dems on 57.
