We present results on the nucleon form factors including disconnected contributions using an ensemble of Nf=2+1+1 twisted mass fermions with a clover term. The ensemble has a spatial extent of 5.12fm (64^3 x128). Techniques such as the summation and the two-state fits have been employed to control possible excited states contamination.
