CMS Cameron McKenna is the first law firm off the blocks to set up a dedicated office in Iran, following the relaxing of EU and UN sanctions against the country last month. The firm is opening an office on Nelson Mandela Avenue in North Tehran, which will be led by partners of CMS Germany. The lifting of sanctions potentially opens up a multi-billion dollar market in oil, software and other goods. Cornelius Brandi, executive chairman of CMS, says: “We see many opportunities, especially in energy, technology and automotive.”
