(ANSA-AFP) - CHISINAU, 01 NOV - Voters in ex-Soviet Moldova went to the polls on Sunday to elect a president under the watchful eye of Moscow which wants the polarised country to remain in its orbit amid political and security crises on Russia's borders. Pro-Moscow president Igor Dodon is seeking a new 4-year mandate, with his biggest challenge coming from longtime pro-Western rival Maia Sandu who wants Moldova to join the European Union. Experts predict a second-round runoff on November 15, as neither Dodon nor Sandu are expected to secure an outright majority on Sunday. (ANSA-AFP).
