Leeds Council said the biggest benefit of the new arena is the employment boost brought to Leeds- through construction jobs, event staffing and the new investment that could be attracted to the city.
On the construction front, at least 200 jobs have been created or safeguarded for Leeds residents and 90 apprentices have worked on building the arena.
