Slaughter and May has won a new client advising construction group Carillion on its acquisition of facilities management company Citex Management Services.

Slaughters became involved in the deal after Carillion hired Richard Tapp as its new head of legal from Blue Circle at the end of last year. Tapp had used the firm at Blue Circle for many years and brought it in to advise on this transaction for Carillion, which generated £609m in 2001 through its business services activities.
