The EUL/NGL group picked up one seat in the election and seven in the subsequent regrouping, raising its total from 34 to 42.
Social Democrats
The PES group did badly, losing 34 of its seats in the election and slipping to the second-biggest group.
Liberals/Liberal Democrats
The ELDR group did moderately well, picking up one seat in the election and seven in the regrouping, giving a total of 50 seats and retaining its place as the third biggest group. The European Radical Alliance (ERA) were not so fortunate and slipped badly, losing eight of its 21 members in the election.
Conservatives/Christian Democrats
The EPP group did well, picking up 23 seats in the election and nine in the regrouping, giving a total of 233 seats and overtaking the left to become the biggest group. To placate the increasingly eurosceptic British Conservatives, the group was renamed "EPP-ED" for the new Parliament, partly resurrecting the name of the former European Democrat group which was merged[1] with the EPP in 1992.
National Conservatives
The Union for Europe (UFE) group slipped during the election and lost 17 seats. The group split[2] during the regrouping, with Ireland's Fianna Fáil and Portugal's CDS/PP forming a new group called "Union for Europe of the Nations". UEN started the Fifth Parliament with 31 MEPs.
Far-Right Nationalists
No explicitly far-right group per se was in existence immediately before or after the election. All far-right MEPs that were elected sat as Independents (see below).
Greens/Regionalists
The Green Group solidified its position, picking up 11 seats in the election to give it 38 MEPs. The European Free Alliance members of the ERA joined with the Green Group to create[3] the Greens/EFA group, which started the Fifth Parliament with 48 MEPs.
Eurosceptics
The I-EN group trod water, gaining six members in the election but losing five in the regrouping, leaving it with 16 members. The group was renamed[4] "Europe of Democracies and Diversities" (EDD) for the new Parliament.
Independents
The Non-Inscrits did badly, losing 20 MEPs to the election. Disparate members (two from Belgium, five from France and eleven from Italy)[5] tried to gain Group privilege by creating a group called the "Technical Group of Independent Members" (full title "Group for the technical co-ordination of groups and the defence of independent members", abbreviated to "TGI" or "TDI"). The attempt initially succeeded, with the group allowed to start the Fifth Parliament until the legal position could be checked.[5] In September, the Constitutional Affairs Committee ruled that they lacked a coherent position ("political affinity", the basis for forming a group) and were disbanded[6] - the only group ever to be forcibly dissolved. The TGI members returned to the Non-Inscrits, increasing their number to 27.[7]
