Nathalie Geneviève Marie Kosciusko-Morizet (French pronunciation: [natali kɔsjysko mɔʁizɛ]) (born 14 May 1973), often referred to by her initials NKM, is an engineer and former politician.

She was also Assistant General Secretary of then majority party UMP and spokesperson for Nicolas Sarkozy in the 2012 presidential election.

As a twenty-nine-year-old, Kosciusko-Morizet was elected a member of the French National Assembly in 2002, representing the department of Essonne, to the south of Paris, serving out the term for Pierre-André Wiltzer who was appointed deputy minister.

In this capacity, she chaired the meetings of G8 energy ministers when France held the group's rotating presidency in 2011.

[4] In 2012, Kosciusko-Morizet left her position as minister to become spokesperson for Nicolas Sarkozy during his presidential reelection campaign.

[7] In the French legislative election of 2017, Kosciusko-Morizet stood in Paris's 2nd constituency, previously held by former prime minister François Fillon.

During the campaign, she was hospitalised for a night after falling on the pavement and hitting her head when a protester threw a batch of election leaflets in her face.

[12] In an interview to the Daily Telegraph in March 2013, she said she held "a lot of admiration" for former British Prime Minister Margaret Thatcher.

[13] Within the Republicans, she has been one of the sharpest critics of the National Front (FN), warning that the party "would disfigure France".

[14] In a 2016 op-ed published by Sunday newspaper Le Journal du Dimanche, Kosciusko-Morizet joined sixteen other high-profile women from across the political spectrum – including Élisabeth Guigou, Christine Lagarde, and Fleur Pellerin – in making a public vow to expose "all sexist remarks, inappropriate gestures and behaviour".
