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'." 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. In May 2016, she criticised the presence of Israeli lobbyists in the
European Parliament: "We can give you a list of all the things we attempted to do, the Israelis are all over this place like a rash." In response the
European Jewish Congress called on
Martin Schulz, president of the European Parliament, to discipline her. Anderson said she meant the word "rash" as a metaphor. In the
2019 European Parliament elections, Anderson was returned on the fifth ballot, after
Diane Dodds of the
Democratic Unionist Party and
Naomi Long of
Alliance. After her seat was abolished due to
Brexit, on 10 February 2020 she became an MLA for Foyle for a second time, after being selected by Sinn Féin to replace Raymond McCartney. On 4 May 2021, Anderson announced she would not be contesting the
2022 Northern Ireland Assembly election, following an internal party review of recent election results in Foyle. She resigned from the Assembly with
Karen Mullan in September and was replaced by
Pádraig Delargy and
Ciara Ferguson. Anderson's sister, Sharon Burke, claimed that Anderson had been used as a "sacrificial lamb" by Sinn Féin. "The British could not do to our Martina what her comrades and friends have done," Burke wrote on
Facebook. ==References==
