Brunswick, which has worked for Northgate for over four years (PRWeek, 25 May 2001) declined to comment on the review process.
However, it is thought Brunswick has replaced Tom Buchanan with former Financial Times media editor Tim Burt as lead partner on the account as a result of the review.
Northgate, whose board of directors includes non-executive director and former security service (MI5) director Sir Stephen Lander, specialises in outsourcing software, particularly for the public sector,
human resources and corporate markets.
The company is set to publish its interim results on 6 December and last month said it would meet market expectations for the full financial year after a strong first half.
Northgate said first-half profits had been boosted by licence sales that had been budgeted for the second half.
It added that the integration of local government software and managed services unit Service and Systems Solutions, which Northgate bought from rival Viridian in April, was proceeding to plan.
