We derive constraints for B{r_arrow}V{sub 1}V{sub 2} modes (V{sub 1,2}=vector meson) that allow a model-independent quantitative assessment of the contributions from electroweak penguin diagrams and/or new physics. The interplay of direct CP with oscillation studies then may lead to the extraction of the angle {alpha}, using B{r_arrow}K{sup {asterisk}}{omega}({rho}) and B{r_arrow}{rho}{omega}({phi}). Any reservation one may have can be explicitly verified in a model-independent way by assuming only isospin conservation. We also briefly mention how the method can be used to extract {gamma} via B{sub s} decays: B{sub s}{r_arrow}K{sup {asterisk}}{rho}, {bar K}{sup {asterisk}}K{sup {asterisk}}. {copyright} {ital 1998} {ital The American Physical Society}
