Marta Andreasen is an Argentine-born Spanish accountant. She was employed in January 2002 by the European Commission as Chief Accountant, and raised concerns about flaws in the commission's accounting system which she felt left it vulnerable to potential fraud. Elected as a Member of the European Parliament for the UK Independence Party (UKIP) in the 2009 election, she defected to the Conservative Party in February 2013. She lost her seat in the 2014 European Parliamentary election.

The 2014 European Parliament election was the United Kingdom's component of the 2014 European Parliament election, held on Thursday 22 May 2014, coinciding with the 2014 local elections in England and Northern Ireland. In total, 73 Members of the European Parliament were elected from the United Kingdom using proportional representation. England, Scotland and Wales use a closed-list party list system of PR, while Northern Ireland used the single transferable vote (STV).
