Peter Terence Richard Ferbrache is an elected Deputy in the States of Guernsey and former president of the Policy and Resources Committee.

The States of Guernsey, officially the States of Deliberation and sometimes referred to as the Government of Guernsey, is the parliament and government of the British Crown dependency of Guernsey. Some laws and ordinances approved by the States of Guernsey also apply to Alderney and Sark as "Bailiwick-wide legislation" with the consent of the governments of those islands. All enactments of the States of Guernsey apply to Herm as well as Guernsey, since Herm is directly administered by the Bailiwick of Guernsey.
