The counsel role was introduced in October 2006 and in the first round last year A&O promoted a total of 17 associates to counsel in London.
In a statement outgoing managing partner and senior partner elect David Morley congratulated each of the new counsel on achieving this "milestone in their career".
The London employment and benefits team and the international capital markets group each gained two new counsel. Each of these departments saw only one partner made up in the latest partnership round in London.
Only one counsel was created in each of corporate and banking, which had dominated the London partnership promotions with four and two new partners each.
In 2007, corporate, banking and international capital markets had scored a massive three counsel promotions each.
Promotions of counsel in A&O's international offices will be announced in due course.
The counsel role was introduced in 2006 to provide an alternative career path for associates and, according to A&O, is intended to "recognise individuals who have a valuable long-term contribution to make to the firm in a role other than partner".
