The QCDSF/UKQCD Collaboration has an ongoing program to calculate nucleon matrix elements with two flavours of dynamical O (a) improved Wilson fermions. Here we present recent results on the electromagnetic form factors, the quark momentum fraction <x> and the first three moments of the nucleon’s spin-averaged and spin-dependent generalised parton distributions, including preliminary results with pion masses as low as 320MeV
