European boxing champion Andrew Selby is on course to defend his flyweight title after guaranteeing himself a medal in Belarus.
The London 2012 Olympian, who lost in the quarter-finals at last year's Games, is aiming to become the first British boxer to retain a level.
And he was a confident winner over Germany's Ronny Beblik, while old rival, Ireland's Michael Conlan, looks equally impressive on the other side of the draw.
Light flyweight Jack Bateson, who has only spent two months on the British podium team, secured a unanimous points win over Ukraine's Vadym Kudryakov to move into the semi-finals.
And super heavyweight Joe Joyce, also making his debut at this level, despatched Hungary's Istvan Ungvari to reach the last four.
However, there was disappointment for light-welterweight Sam Maxwell and Scottish lightweight Charlie Flynn, who lost their quarter-finals.
