The decay B → K*l^+l^-, where the l^+l^- can be e^+e^- or μ^+μ^-, resulting from the b → s flavour changing neutral current decay is highly sensitive to the presence of new physics. The angular observables describing the K* polarisation (FL) and the forward backward asymmetry (AFB) are first measured in two regions of di-lepton mass squared using a dataset of 384 million BB pairs collected by the BaBar detector on the PEP-II rings at SLAC. A second measurement was made in four regions of di-lepton mass squared using a dataset of 468 million BB pairs.
