Former Financial Times Group journalist Wraight also previously edited The International and was deputy editor of Financial Adviser. His PR experience includes heading comms at actuarial and HR consultant Towers Watson and at UK accountancy firm Robson Rhodes.
In October it was announced that UK-based Spada is to merge with US legal specialist Infinite PR, in a move that will create a Transatlantic consultancy called Infinite Spada with an initial turnover of more than $7m (£4m).
Infinite Spada chief executive Gavin Ingham Brooke said: "Jamie [Diaferia, founder of Infinite] and I welcome Bruce to the team, confident that he will make a great contribution. His experience is directly relevant to many of our clients, spanning as it does major law firms, pensions and asset management companies and accountancy firms.
"His expertise in advising financial services and law firms on global communications issues is a further bolstering of our international and dual national capability."
Wraight said: "It’s great to be joining a consultancy whose ambitions are so closely aligned with my own. Infinite Spada is an exciting combination of two front-ranked professional services communications firms – with a major corporate and reputation management practice."
