Competition litigation in London

Hausfeld & Co LLP

Hausfeld & Co LLP garners praise as ‘the leading competition litigation firm acting on the claimant side’. It excels in antitrust damages claims at UK and European level. The London-based group is increasingly present in the courts in the Netherlands, France and Spain, where it often works with local litigators. In a significant development, Scott Campbell was appointed as the head of the competition disputes department in October 2019. The team also includes London managing partner Anthony Maton, who is seen as ‘a trailblazer’ in the area of private competition law enforcement in the UK. Lesley Hannah, who is particularly prominent in the technology sector, ‘combines a great eye for detail with strategic and tactical vision for each case’. The ‘very able, pleasant, diligent and commercialAnna Morfey specialises in claims arising from alleged cartels in the trucks and the automotive industries. Nicola Boyle has had a leading role in pursuing claims on behalf of UK retailers against MasterCard and Visa in relation to unlawful interchange fees. Boyle and recently promoted partner Tom Bolster are also key contacts for multijurisdictional claims. In 2019, the group continued to expand, with there being a number of hires at counsel and associate level.

Scott Campbell


In London, Hausfeld is the leading competition litigation firm acting on the claimant side. The team has over a decade of experience. The firm has offices elsewhere in Europe, which allows it to take a pan-European approach to managing claims.

This excellent team is very easy to work with – it combines tactical acumen with a very pleasant manner. We regard the team as the leading practice in Europe on the claimant side dealing with antitrust damages claims.

The team is hardworking and dedicated to securing a good outcome for its clients. It has a huge amount of experience in handling class action claims and understands the complexity of managing such litigation.

Anthony Maton is at the absolute top of his game.

The recruitment of Scott Campbell in 2017 was useful to the firm, as he brought a wealth of competition litigation experience with him.

Nicola Boyle is a very effective litigator and a diligent case manager, with a very good overall strategic vision.

Anna Morfey is very able, pleasant, diligent and commercial.

Practice head(s):

Richard Swallow


Slaughter and May is undoubtedly up there with the very best competition litigation teams in the City of London. The group offers unrivalled quality and strength of engagement at all levels.

In my experience, Slaughter and May’s team is particularly strong in two respects. First, the quality of work produced is excellent – the lawyers nail down the issues and really provide first-class output. Second, the group has significant resources both at partner and associate level: this is definitely a team with sufficient firepower to do a really good job.

As it is well known in the industry, Slaughter and May’s litigation department is involved in many of the leading commercial and competition claims before the English courts. It stands out from other firms as having uniformly able solicitors at all levels of seniority, from trainees to partners. The department has won key roles in two of the largest claims currently before the English courts: the trucks claim and the FX claim, both of which include cutting-edge collective actions.

The team led by Camilla Sanger delivers excellent service, keeps calm even under the most relentless stress, and sees several moves further ahead than the opposition.

Richard Swallow is the doyen of the department in this field; he is immensely skilled and experienced.

Holly Ware is a dynamic and proactive partner, hugely capable and delightful to work with.

Claire Jeffs is a fantastic lawyer, an utterly unflappable and excellent presenter.

Damian Taylor is a brilliant litigator and partner who is surely one to watch as a future superstar.

Mark Molyneux

Other key lawyers:

Bruce Kilpatrick; Rona Bar-Isaac


The Addleshaw team are consistently excellent across all levels and this wide range of competition litigation matters. They are excellent at project delivery, and write compelling submissions to courts and regulators (including developing compelling evidence) and are good advocates. They guarantee active partner engagement across all matters, focus on securing great outcomes and give crystal clear advice (and do not sit on the fence). The emphasis on work being partner-led supports them being laser-like focused on the matters and issues that make the most difference to case outcomes. They are also excellent at project management and working with them is always stress-free. In short, they have a standout team.

We have worked with multiple partners over the last year, namely Bruce Kilpatrick, Rona Bar-Isaac, and Mark Molyneux and range of associates (particularly Neil O’Sullivan and Jake Minards-Tonge as regards litigation). Bruce is a market leader; he is very clever, thinks matters through carefully (taking on board and developing the ideas of clients and other advisors), and is really good at developing the case. Rona is very strategic as to the key evidence to hand, and she deserves much credit for persuading the CMA to drop two investigations against her pharma client. Mark Molyneux fits in really well with the competition team and provides seamless and integrated competition/litigation advice. As part of his team, Neil has done an excellent job in managing a complex piece of competition litigation and Jake has forensically unpicked all the difficult economic/disclosure issues on a cartel case.’

The team’s client interaction skills are superb. They seamlessly integrate and become an extension of our own practice. I find them so easy to deal with. Most law firms are not like this. Technical skills of the team are first-rate, as you would expect. They are able to handle ‘big ticket’ litigation and have the strength and depth to manage all elements of litigation.

Mark Molyneux – heads up the team and is a litigator who has superb strategic skills. He is very user-friendly and has an ability to see and articulate the pros and cons of proposed courses of action and provide leadership by pinning colours to the mast.

Samatha Haigh – Associate Director – takes ownership of tasks/thorny issues and delivers solutions. Her technical and drafting skills are fantastic.

James Currie – Associate – one to watch. A very capable lawyer who is unflappable
