Britain, caught in the crossfire of a damaging trade dispute between plane makers Boeing and Bombardier, said on Sunday it would fight its corner to protect thousands of jobs put at risk in Northern Ireland.

Trade minister Liam Fox said Britain was working to find a resolution after the United States last week responded to a complaint by Boeing by imposing a 220-percent preliminary duty on Bombardier's CSeries jets, whose wings are made in Belfast.

"We've said that we will fight our corner," Fox told the annual Conservative Party conference. "We've been caught in the crossfire of a much larger dispute."
