(ANSA) - ROME, NOV 17 - (refiling to fix typo in slug, history of regions) Some 4.3 million Italians are called to the polls Sunday and Monday for regional elections in Emilia-Romagna and Umbria which will be another key test for the national government and opposition after last month's election in Liguria which saw the centre right narrowly prevail.
    The centre-right candidates are backed by Premier Giorgia Meloni's right-wing Brothers of Italy (FdI) party, Deputy Premier and Transport Minister Matteo Salvini's right-wing League party, and Deputy Premier and Foreign Minister Antonio Tajani's centre-right Forza Italia party.
    The centre-left candidates are supported by the so-called 'broad field' of Elly Schlein's centre-left Democratic Party (PD), former two-time premier Giuseppe Conte's anti-establishment 5-Star Movement (M5S), the Green-Left Alliance (AVS) of Angelo Bonelli and Stefano Fratoianni, and centrist groups Azione of former industry minister Carlo Calenda and Italia Viva (IV) of former premier and ex centre-leaning PD chief Matteo Renzi.
    A centre-right win in Emilia Romagna would be a seismic shock for the region, which with Tuscany is only one of two regions that has always leaned leftwards in the 54-year history of the regions, which were set up in 1970 and up and running two years later.
    The centre-left candidate in the northern region, Ravenna Mayor Michele de Pascale, is well ahead in pre-election polls of the centre right's Elena Ugolini, an independent head teacher with roots in the Catholic activist group Communion and Liberation (CL).
    The elections in Emilia-Romagna have been brought forward a few months after the election to the European Parliament of former centre-left governor and current PD chair Stefano Bonaccini, who in any case could not have stood for a third time.
    In Umbria the centre right is bidding to retain control of the region which it took for the first time with the League's Donatella Tesei five years ago.
    Incumbent Tesei, a civil and administrative lawyer who is the former mayor of the small town of Montefalco, is up against the centre left's Stefania Proietti, an engineer and researcher who is the current mayor of Assisi and president of the province of Perugia.
    The controversial right-wing mayor of Terni, Stefano Bandecchi, was running with his small right-wing Popular Alternative party but has now switched his support to Tesei and could swing the result in her favour, some pundits say.
    Pre-election polls in the central region were too close to call.
    Meloni is hoping the centre right's long winning run in regional elections, aside from one blip, will continue.
    Since it took office two years ago her rightwing coalition has prevailed in 11 out of 12 local elections if June's European elections are included.
    The sole centre left win has been in Sardinia. (ANSA).
