Almost 100 jobs are being cut in Belfast by aircraft manufacturer Bombardier.

Managers and professional support staff will be affected, a company statement said. 

The redundancies are not related to the firm's trade dispute in the US but centre on the outsourcing of IT services, union leaders added. 

"Following the 7,500 global workforce reductions announced by Bombardier last October, we have reviewed our manpower requirements in Belfast and regret to confirm that we must reduce our workforce levels by up to 95," a statement from the company said.

Last year, Canadian-based Bombardier said it was cutting 1,000 jobs in Northern Ireland, around a fifth of its workforce there.  

Bombardier, which employs almost 5,000 people in Belfast and accounts for 10% of Northern Ireland's manufacturing exports, is facing significant costs in the fallout with US aeronautics powerhouse Boeing.

The dispute centres over Boeing's allegations that Bombardier received subsidies allowing it to sell its C Series planes at below-market prices.

The US Department of Commerce is expected to announce a decision on whether to impose duties against Bombardier on September 25.
