CMS Cameron McKenna has signalled its intentions to bulk up in Aberdeen with an ultimately unsuccessful bid to take over oil and gas specialist Paull & Williamsons.

Camerons spent several months in talks with the Scottish firm, reflecting the current appetite among major firms for ramping up in the city.

The talks come less than a year after much of Paull & Williamsons’ main competitor in Aberdeen, Ledingham Chalmers, merged with Scottish heavyweight McGrigors.

The talks collapsed last month. The deal would have given Camerons’ upstream oil and gas practice a major boost as Paull & Williamsons has a particularly strong client base among oil field services companies.

The 30-partner Scottish firm also counts BP among its client base, as does Camerons, and in partner Bruce McLeod it features a former BP in-house lawyer in its ranks.

Paull & Williamsons also has a significant private client team, which includes a residential property services practice, but neither are likely to have been attractive to Camerons.

“It is unlikely that there could have been a merger without either significant redundancies or some kind of split of Paull & Williamsons,” said one Aberdeen-based partner.

Neither Camerons nor Paull & Williamsons made any comment.
