In January 2014, Reding publicly announced that she has no plans to seek the nomination of the centre-right European People's Party for the presidency of the European Commission and that she supports the candidacy of fellow centre-right Luxembourger Jean-Claude Juncker. Johannes Hahn twice served as Acting Commissioner in her stead, from 19 April 2014 – 25 May 2014 while she was on electoral campaign leave for the 2014 elections to the European Parliament, and 1 July 2014 – 16 July 2014 after she took up her seat.
