Jones was placed first on the party list in South East Wales at the 2016 National Assembly election. As Labour won 7 out of the 8 single member constituencies, Labour was not entitled to any extra seats from the Additional Member list, and Jones was not elected. Jones voted to Remain in the 2016 referendum. She argued following the referendum for the Prime Minister to seek a cross-party "consensus" on leaving the European Union, but says she is opposed to a "damaging Tory Brexit or a no deal outcome". She says that if "Parliament to achieve a sensible Brexit", she would support a People's Vote. Jones was nominated as Labour's Parliamentary candidate for a third time, on this occasion for Newport West in January 2019 and was elected as an MP in April 2019 in the Newport West by-election, which had been caused by the death of the sitting Labour MP, Paul Flynn. On a relatively low turnout of 37.1%, Jones took 39.6% of the vote, although the Labour majority dropped from 5,658 to 1,951. She was officially sworn in and took her seat in the House of Commons on 8 April 2019, and made her maiden speech on 1 May 2019 in a debate on climate change. Her constituency office at The Estates Office on Gold Tops was opened in June. Jones stated in 2019 that she supported the now-cancelled M4 relief road in order to relieve traffic congestion on the M4 motorway.. Jones became a member of the Environmental Audit Select Committee in May 2019. She has signed the Long Live the Local pledge to reduce beer duty and business rates. In August 2019 Jones joined 100 other MPs in calling for Prime Minister Boris Johnson to recall Parliament from the Summer Recess, and was one of 148 Labour MPs who wrote to the Prime Minister demanding he reverse the decision to prorogue Parliament in October for a Queen's Speech prior to the October 31 Brexit date. She voted in favour of the Benn Act, aimed at requiring an extension to Article 50 at the end of October to prevent a no deal exit on 31 October. Jones was re-elected in the 2019 United Kingdom general election on a slim majority of 2.1%.
