Management consultancy Accenture is cutting 300 to 400 jobs, many of which could be IT jobs.
The firm confirmed it would be making redundancies, but said the consultation process would determine whether they are from the systems integration and technology unit or other parts of the business.

It said the cuts are an attempt to "balance the skills of our workforce" rather than a response to worsening economic conditions.
A spokesman for the firm said, "Managing supply and demand of our resources remains a top priority. We are taking steps in the UK to balance the skills of our workforce against client needs.
"Given this, we expect a workforce reduction of approximately 300-400 people in certain skill sets where we have excess capacity. Those who could potentially be affected have been notified.
“This is about rebalancing our UK headcount, we continue to hire at the same time. It is not necessarily the case that we will be 300-400 fewer in the UK.
"We continue to recruit in the UK for other skills in which we need additional capacity to meet demand."
