Competition law compliance is a high priority for businesses worldwide. Competition authorities are increasingly cracking down on cartels, abusive behaviour and other anti-competitive practices, as well as strictly enforcing their merger control rules. No company or individual can afford to ignore the civil and criminal sanctions that may be applied under the competition rules.
Our competition team is recognised by clients and peers for providing the highest quality advice across the full spectrum of EU and UK competition law matters. We regularly advise on merger control issues stemming from M&A and PE acquisitions, joint ventures and other transactions from both a UK / EU and multijurisdictional perspective.
Our team has advised on formal competition investigations as well as market studies and investigations. We also have vast experience advising and defending companies involved in international cartels and abuse of dominance investigations by various competition authorities in the UK and EU. Along with this, we are experienced in appealing antitrust decisions to the European Courts.
