New high-precision measurements of p({gamma}-vector,{pi}) and p({gamma}-vector,{gamma}) cross sections and beam asymmetries have been combined with other polarisation ratios in a simultaneous analysis of both reactions. The E2/M1 mixing ratio for the N{yields}{delta} transition extracted from this analysis is EMR=-3.0%{+-}0.3(stat+sys){+-}0.2 (model)
