text: 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.
