impeccable conduct

Today, however, my thanks are especially significant. I have learned a great deal from Mr Martens' impeccable conduct as a parliamentarian.

Lightning won effortlessly but Harrier's skilful archery and impeccable conduct impressed him so much he offered the loyal young man the next stewardship of his estate.

Throughout my life I have consistently opposed all forms of wrongdoing and I believe, Colonel Sabri, that my impeccable conduct thus far gives me the right to criticize anything I see fit.
