In September 2014 King's College London opened King's College London Mathematics School, a free school sixth form located in Lambeth that specialises in mathematics. In October 2014, Ed Byrne replaced Rick Trainor as Principal of King's College London, the latter having served for 10 years. In December 2014, King's announced its plans to rebrand its name to 'King's London'. It was emphasised that there were no plans to change the legal name of King's, and that the name 'King's London' was designed to promote King's and to highlight the fact that King's is a university in its own right. King's announced that the rebranding plans had been dropped in January 2015.
