Milanović se smatra odlučnim a ponekad i tvrdoglavim političarom, koji time ponekad iritira "staromodne" fakcije u okviru SDP-a, koje više vole raspravu i analizu od brzog odlučivanja.
Milanovic is viewed as a decisive and sometimes stubborn politician, thereby sometimes irritating "old-fashioned" factions within the SDP who prefer debate and analysis to fast decision-making.
