                      using non-perturbatively O(a) improved Wilson fermions. The
                      calculations are done for a wide range of pion masses and
                      lattice spacings. We check for finite size effects by
                      repeating some of the measurements on smaller lattices. The
                      large number of lattice parameters we use allows us to
                      extrapolate to the physical point. For the square of the
                      charge radius we find $<r^2>=0.441(20)$ $fm^2,$ in good
                      agreement with experiment.},
