Simmons & Simmons advises across the full spectrum of competition law, including merger control, cartel investigations, competition infringement, and state aid matters. The TMT and financial services sectors remain particular focal points for the practice. Practice head David Trapp is well regarded for his expertise and experience in both contentious and non-contentious competition issues. Duncan Green, praised for his ‘enormous knowledge’, is also recommended. The team saw changes in personnel with the departure of Satyen Dhana and the retirement of Mark Jephcott in October 2024.
