Factbox: Who's who on the new EU executive

(Reuters) - The European Parliament is due to vote on Oct. 22 on whether to confirm in office the incoming European Commission, the EU executive to be led by Jean-Claude Juncker.

EU government leaders must first approve Juncker's proposal to take a new Slovenian nominee, Violeta Bulc. She and Slovak Maros Sefcovic would then face confirmation hearings, a source close to Juncker said on Tuesday.

Each of the 28 member states nominates a commissioner. The provisional line-up proposed by Juncker is as follows:

PRESIDENT JEAN-CLAUDE JUNCKER

Luxembourg, center-right, 59. Prime minister for 19 years. Confirmed in office by parliament after nomination by national leaders in July over British objections. He wants to centralize power, promises a "political not technocratic" Commission focused on reviving the economy and regaining trust of voters who backed a host of anti-EU parties in the European Parliament election in May.

FOREIGN AFFAIRS CHIEF FEDERICA MOGHERINI

Italy, center-left, 41. Nominated by EU governments despite reservations in Eastern Europe that she is soft on Russia, a key gas supplier for Italy. Promises youthful energy, to hold Moscow to account over Ukraine and engagement with Iran and the Arab world. At a confident hearing last week, she said the EU should "deeply reassess" relations with Russia in the coming five years.

FIRST VICE-PRESIDENT FRANS TIMMERMANS

Netherlands, center-left, 53. Juncker's "right-hand" with a roving brief to keep order in the new, two-tier hierarchy, charged with delivering Juncker's promises. Former diplomat, foreign minister, prodigious linguist, including Russian learned on military service. Lawmakers say he will add fostering sustainable development to his brief to ease environmentalists' concerns about the new energy and climate change commissioner.

VICE-PRESIDENT, BUDGET, KRISTALINA GEORGIEVA

Bulgaria, center-right, 61. Former World Bank economist, ran humanitarian affairs in outgoing Commission after last-minute nomination prompted by parliament's rejection of Sofia's first choice. Competence in office, plus gender, meant she was long tipped for high office. Won center-left backing after hearing.

VICE-PRESIDENT, ENERGY UNION, MAROS SEFCOVIC

Slovakia, center-left, 48. Outgoing commissioner responsible for EU institutions. Former diplomat in Brussels and Israel, a graduate of Soviet, French and U.S. universities. Originally offered the transport brief, a source close to Juncker said he was to be offered this more senior post after parliament blocked Slovenia's Alenka Bratusek for the role. New Slovenian nominee Violeta Bulc is in line for transport in place of Sefcovic, who is likely to face a confirmation hearing on Tuesday, Oct. 21.

VICE-PRESIDENT, JOBS & GROWTH, JYRKI KATAINEN

Finland, center-right, 42. Prime minister until June and outgoing EU economy commissioner, he's a fiscal hawk in the euro zone, close to German Chancellor Angela Merkel. Will oversee Moscovici, who hopes to take over his economics portfolio, as well as Hill, Thyssen, Bienkowska, Cretu and others.

VICE-PRESIDENT, EURO & SOCIAL DIALOGUE, VALDIS DOMBROVSKIS

Latvia, center-right, 43. Physicist turned bank economist, finance minister and, until January, the prime minister who kept power despite deep pain inflicted on the crisis-ravaged Baltic state so it could join the euro zone. Resigned over deadly collapse of a Riga supermarket building. Another fiscal hawk, he would also oversee commissioners Moscovici, Hill, Thyssen, Bienkowska and others. At his hearing, he defended the benefits of the euro, while noting that there was no law to prevent states giving up the currency.

VICE-PRESIDENT, DIGITAL SINGLE MARKET, ANDRUS ANSIP

Estonia, centrist, 58. Qualified chemist and former Soviet Communist party member, he was prime minister for nine years until stepping down in May, retaining popularity despite hardships of qualifying for using the euro in 2011.
