Carlos qualified from Zaragoza (Spain) in 1992 and came to the UK in 1995 at the height of the BSE crisis. For over three years he worked on meat plants in the West Country as an OV, mainly running BSE-related schemes like the Over Thirty Month (OTM) and the Calf Processing Aid Scheme (CPAS).

After a move to Essex in 1999, Carlos started working for the City of London Corporation as an OV at the Border Control Posts (BCPs) of Tilbury and Thamesport, and at London’s Smithfield Meat Market.

In 2004, he went to Poland to help one of their new BCPs to get ready for the accession day, and to supervise its functioning on the first weeks of Poland becoming a new EU member state.

Since 2006, Carlos has been the Senior OV with the City of London Corporation, where he manages a team of (currently) ten OVs. During this time he has gotten involved in the development and construction of London Gateway Port and its BCP, which is now the second largest container terminal in the UK. He has also been involved in the preparations for Sanitary and Phytosanitary (SPS) checks on EU cargo and – more recently – in the new SPS checks regime for EU and the Rest of the World.
