A major jobs announcement is expected to be made next week following the recent visit of US Secretary of State Hilary Clinton to Northern Ireland.

Details of the US investment are being kept under wraps, but it will be seen as a vote of confidence in NI's political process.

Stormont ministers have been lobbying hard in the US for more investment as part of the peace dividend.

It is understood the deal will mean several hundred new high end jobs.

Northern Ireland's politicians have spent years lobbying American political and business leaders to invest in Northern Ireland.
