Democrats (PD) and Liberal Democrats (PLD) signed a political and parliamentary protocol containing 10 points on Monday, news agencies report.

Representatives of the two parties announced their plans for such a collaboration two weeks ago but declared that it couldn't be approved until the DA Alliance, the former alliance between the Democrats and the Liberals made up for the 2004 elections, was dissolved.

The Democrats were a member of the DA governing coalition with the Liberals until they were removed from the government in a reshuffle at the height of a major political crisis this spring.

The Liberal Democrats is a political group formed of members of the Liberal Party (PNL) who were ousted over the past year over their close ties with the Democrats and President Traian Basescu, who's been at loggerheads with Liberal PM Calin Popescu Tariceanu for about two years.

The two parties have already collaborated in the parliamentary session that just ended. PD and PLD co-signed a simple motion debated in the last weeks' session and have similar options regarding the vote for normative acts.

Last months, the two decided to take part separately in European Parliamentary elections to be held later this year.
