text: Political career In 2007, Anderson was elected to the Northern Ireland Assembly as a Sinn Féin member for Foyle, along with Raymond McCartney.
  In May 2007, Anderson became one of the first Sinn Féin members to join the Northern Ireland Policing Board.
  In December 2007, Anderson said she was concerned that large numbers of migrant workers from mainly Catholic countries were being classed as 'Catholic/nationalist' in monitoring forms, rather than 'other'. She said "Given that the entire basis of the legislation around monitoring was put in place to identify imbalances in the workforce between the local Catholic/nationalist and Protestant/unionist communities it is therefore vital that given the addition of migrant workers in the workforce, that they should clearly be categorised as having a community background of 'other'."
  Employment monitoring by the Equality Commission records solely religion, and not political affiliation.
  She was selected by Sinn Féin to fight the Foyle constituency at the 2010 Westminster general election. She lost to the SDLP incumbent, Mark Durkan, by 5,000 votes (11% of the vote). In May 2012 it was announced that she would be replacing Bairbre de Brún, as MEP for Northern Ireland. Anderson retained her MEP seat in the 2014 election, topping the poll with 159,813 first-preference votes.
