Deloitte announced that its Belgian, Danish, Dutch, Finnish, Icelandic, Norwegian and Swedish member firms will combine with the UK and Swiss firm to create Deloitte North West Europe.

Deloitte North West Europe will come into effect on 1 June 2017 and will have 28,000 staff, and will be expected to generate over $5.6bn worth of revenues annually.

Deloitte will invest $224m across the region towards the project over the next three years.
