A guide to UK and EU competition law for overseas clients

24 Aug 2015

UK and EU competition law is not only relevant to large undertakings.

On the behavioural side, an anticompetitive agreement or an abuse of dominance may be unlawful even if the affected geographic market is small.

On the compliance side, a merger may require approval if the merged entity is likely to have a 25% market share in only part of the UK, possibly even a single town.

Even those whose activities have no competition law aspect can be victims of others' behaviour.

This guide covers three of the four cornerstones of competition law:

  1. "Article 101" anticompetitive agreements between undertakings.
  2. "Article 102" abuse of dominance by a single undertaking.
  3. The regulation of mergers.
