The Serjeant-at-Arms of the House of Commons is responsible for security matters concerning the House of Commons. The Serjeant, whilst in the Commons overseeing proceedings, can also escort MPs out of the chamber by order of the Speaker of the House. The post dates back to 1415, and has often been held by retired military or police figures (though in recent years those from a civil service background have been appointed). The current Serjeant-at-Arms is Ugbana Oyet (appointed in October 2019); he was previously an electrical engineer in Parliament.
