Lynn grew up in Tallaght, Dublin. While not party political, her parents instilled in her from an early age a deep understanding of social justice and equality. At the age of 12 Lynn's first act of political activism was to write to the Evening Herald supporting the Dublin Bus strikers.
Lynn studied journalism before going on to obtain qualifications in Environmental Resource Management, Environmental Impact Assesment and Environmental Conservation Management.
On completing her studies, she moved to Kerry and worked in Killarney National Park with Groundwork, an environmental NGO and then with the Killarney National Park Education Centre.
It was in Kerry that Lynn first joined Sinn Féin. And in the years of 2007 and 2009 Lynn made attempts at both the general and local elections. She was unsuccessful and following Ireland's financial crash she returned home to Dublin and involved herself with environmental community work.
Lynn like many was angry about the direct impact Ireland's Celtic tiger and the banks imposing income equality had on Ireland. She manifested her anger into activism. She mobilised, organised and became the voice of Ireland's disaffected. Representing the change the country so desparately needed. In Ireland's 2014 European Election, Lynn topped the polls with 83,000 first preference votes. She sits on the Environment, Public Health & Food Safety Committee and the Committee for Employment & Social Affairs.
Since her election Lynn has championed the cause of the people. She has been a watchdog in the EU for Irish citizens. She led the negotiations on the Right to Water report in the EU Parliament and continues to campaign at a national and EU level for an end to water charges, privatisation and for water to e recognised as a human right.
She relentlessly campaigned to end the incarceration of Dublin schoolboy Ibrahim Halawa in Egypt. Successfully getting the EU Parliament to call for his release she travelled to Egypt to visit him in prison before he was finally released.
She has persistently challenged the Irish Government on Ireland's lack of media diversity, and the threat to it's plurality due to a concentrated ownership.
During the Repeal campaign, she canvassed across the country and continues to campaign for abortion rights for the women in the north of Ireland.
Lynn actively campaigns for the families of the victims who lost their lives in the Stardust Tragedy in 1981. Lynn and the families and survivors are campaigning for a fresh inquest into the cause of their deaths. They are determined to get justice for the 48.
