Simon Hart was re-elected the Conservative Member of Parliament for Carmarthen West and South Pembrokeshire for the third time in June 2017 with a majority of just over 3,000. He is a member of the Digital, Culture, Media and Sport Select Committee ; of the Committee on Standards in Public Life and several All Party Parliamentary Groups.

Prior to being elected, Simon was Chief Executive of the Countryside Alliance, Europe's largest rural affairs lobby group, for seven years. He took over as its Chairman in September 2015. His long-standing interest in learning outside the classroom has been reflected in his chairmanship of a charitable group that works with Government on this subject and his appointment as an educational consultant to the Countryside Alliance.

He also previously worked as a chartered surveyor in Carmarthen and Haverfordwest and served with the Territorial Army for seven years.

He is 54 and lives in Llanmill near Narberth with his wife and two children.
