No firms were dropped from the panel as a result of the review.
Group general counsel Margaret Coltman, who previously worked at Lloyds Banking Group and was a partner at Norton Rose before joining Prudential in 2009, led the review alongside director of group legal Simon Ramage.
It is understood that new UK legal head Guy Dunlop is set to review Prudential’s UK panel.
A Prudential spokesman said: “Like any other major international company, Prudential works with a variety of legal service providers. We regularly review these in line with our requirements.”
