Steve Wozniak: Apple co-founder at Londonderry event
Apple co-founder Steve Wozniak is due to address one of the biggest European business events, which is being held in Londonderry on Thursday.
Mr Wozniak, who founded Apple along with Steve Jobs and Ronald Wayne, is the headline speaker at the European Business Network (EBN) congress.
The event, which is held over two days, is expected to attract delegates from all over the world.
This will be the first time Mr Wozniak has spoken in Northern Ireland.
It is also the first time this major programme of events will have been held in Northern Ireland.
Event organisers said they were partly attracted to the location because of Derry's status as UK City of Culture.
