Investigations are underway after Northern Ireland's wealthiest businessman was killed in a helicopter crash.

Edward Haughey from Rostrevor in County Down was among four people to die in the accident in England.

He served as a member of the Seanad for a time, before being appointed to the House of Lords.

The 70-year-old, born in Co Louth, set up the Norbrook Laboratories in Newry, which employs over 1,000.
