Answer
The UK Independence Party (UKIP) was represented by Nigel Farage, not Hamilton. Hamilton represented the Conservative Party. Nigel Farage was a Member of the European Parliament (MEP) for the South East England constituency from 1999 to 2004 and again from 2009 to 2019. During his time as an MEP, he served as UKIP's leader and was a vocal critic of the European Union.
