Dame Diana Ruth Johnson DBE (born 25 July 1966) is a British politician who has served as the Member of Parliament (MP) for Kingston upon Hull North since the 2005 general election.

[8] In 2014, Johnson proposed a Bill under the Ten Minute Rule that would require sex and relationships education, including discussions around issues such as consent, to be made a compulsory part of the National Curriculum[9] Johnson was appointed in September 2015 by Jeremy Corbyn, shortly after he became Labour party leader, as a shadow minister in the Foreign and Commonwealth team.

[10] In late June 2016, along with colleagues, she resigned as a shadow minister, unhappy at Corbyn's leadership following the 'leave' vote in the European membership referendum.

[20] In November 2021, Johnson in the Jewish News wrote an article supporting a speech by Keir Starmer that opposed the Boycott, Divestment and Sanctions of Israel.

She said "Rejecting anti-Zionist antisemitism means opposing the BDS movement which demonises and delegitimises Israel, singling it out for boycotts and sanctions.

[23] Johnson was also criticised by 800 medical professionals in a letter that suggested such an amendment would remove legal safeguards for both the mother and child and pointed out that extensions to the 24 week limit were only supported by 1% of the UK population according to a recent Savanta ComRes poll.

[24] In 2024, Johnson's amendment to the Criminal Justice Bill, which would decriminalise women themselves in relation to their own pregnancies but would leave the rest of abortion law and regulation unchanged, has been backed by the Royal College of Obstetricians and Gynaecologists, the British Medical Association, Mumsnet, and many groups who work with survivors of gender based violence such as Women's Aid and Karma Nirvana.

[25] Conservative Chancellor Jeremy Hunt, who has previously backed a reduction in abortion time limits, has indicated he may support her amendment.

[29] Johnson was appointed Dame Commander of the Order of the British Empire (DBE) in the 2020 New Year Honours for charitable and political service,[30] in part for her campaigning on contaminated blood transfusions.
