At the
2010 general election, McKinnell was elected to Parliament as MP for
Newcastle upon Tyne North with a vote share of 40.8% and a majority of 3,414. In October 2010, the Labour Leader
Ed Miliband appointed McKinnell to the role of
Shadow Solicitor General, where she was responsible for the party's response to the
News International phone hacking scandal. She raised questions about the
Crown Prosecution Service's handling of the scandal, including a question to the
Attorney General in the House of Commons asking why the CPS had refused for so long to admit that there were grounds to bring prosecutions. In October 2011, during a shadow ministerial reshuffle, McKinnell was made shadow children's minister, shadowing
Tim Loughton. In that post she criticised the adoption process as too slow and called for immediate improvements in support for social workers and family courts to speed up the process. She also accused the government of doing too little to help children for whom adoption was not suitable and following this, requested a guarantee that the government would give priority to placing children in "happy homes." In June 2012, after the resignation of
Peter Hain, she was then moved to become Shadow Exchequer Secretary to the Treasury, replacing
Owen Smith. McKinnell backed a campaign by
ActionAid on international tax laws and tabled amendments to the Budget which would have required the government to monitor the impact on developing countries of changes to so-called Controlled Foreign Companies regulations. She said, "It seems a false economy to invest ... in changes that will undermine the very progress towards which our international aid money, which increases year on year, is going". Also in June 2012, McKinnell publicly criticised
Take That singer
Gary Barlow following newspaper allegations of
tax avoidance made against him. McKinnell agreed that Barlow should consider returning his recently awarded
OBE if allegations of tax avoidance were proven "because it doesn't send out the right messages to ordinary people who are paying their fair share of tax". At the
2015 general election, McKinnell was re-elected as MP for Newcastle upon Tyne North with an increased vote share of 46.1% and an increased majority of 10,153. McKinnell was made
Shadow Attorney General in September 2015 by Labour leader
Jeremy Corbyn, but resigned in January 2016, citing party infighting, family reasons and the ability to speak in parliament beyond her legal portfolio. She supported
Owen Smith in the failed attempt to replace
Jeremy Corbyn in the
2016 Labour Party (UK) leadership election. McKinnell has been a prominent campaigner for the
Women Against State Pension Inequality campaign. In December 2015, following the acceleration of the equalisation of the State Pension Age, she argued that the acceleration has happened too quickly and left female pensioners uncertain. McKinnell was also made Vice Chair of the recently established
All-Party Parliamentary Group on the WASPI campaign. At the snap
2017 general election, McKinnell was again re-elected with an increased vote share of 55.4% and an increased majority of 10,349. She was again re-elected at the
2019 general election, with a decreased vote share of 45.4% and a decreased majority of 5,765. In September 2020, McKinnell was appointed a vice-chair of
Labour Friends of Israel. In the
2023 British shadow cabinet reshuffle she returned to the frontbench as Shadow Schools Minister, replacing
Stephen Morgan. At the
2024 general election, McKinnell was again re-elected, with an increased vote share of 50.3% and an increased majority of 17,762. She served as
Minister of State for School Standards from 2024 to 2025. She left the government in the
2025 British cabinet reshuffle. ==References==
