Name that MP

Any idea which senior MP said this?

"It is of the greatest importance that the conduct of Members of the House meets, and is seen to meet, the high standards expected by the Wicks committee, and also by our constituents. Lapses, however rare, are very damaging to public confidence in the House and in our parliamentary democracy. If lapses occur, and are not seen to be tackled with sufficient rigour, the effect is many times worse. Our system for regulating standards of conduct must be transparent, fair and effective."
