Electromagnetic form factors and axial charge of the nucleon from Nf = 2 + 1 Wilson fermions

We present an update on our determination of the electromagnetic form factors and axial charge of the nucleon from the Nf = 2 + 1 CLS ensembles with increased statistics and an additional finer lattice spacing. We also investigate the impact of O(a)-improvement of the currents.
