Add to ORKGWe report on preliminary results of a high statistics quenched lattice QCD calculation of nucleon matrix elements within the Symanzik improvement programme. Using the recently determined renormalisation constants from the alpha collaboration we present a fully non-pertubative calculation of the forward nucleon axial matrix element with O(a) lattice artifacts completely removed. Runs are made at #beta# = 6.0 and #beta# = 6.2, in an attempt to check scaling and O(a"2) effects. We shall also briefly describe results for left angle x right angle, the matrix element of a higher derivative operator.
