G8: New report says final cost for Fermanagh summit was £92m
The bill for hosting the G8 in Fermanagh has been revised upwards to £92m, according to a new report.
The previous official estimate was £80m.
The review of the two-day summit held in Enniskillen in June 2013 said less than half the cost or £40m was spent within the local economy.
A quarter of the money spent (£23m) was funded from the Northern Ireland public purse.
According to the report, commissioned by the Northern Ireland Executive and seen by the BBC, the final cost of hosting the event was an estimated £92m.
Altogether 8,600 police officers were on duty during the event.
Security costs accounted for the largest proportion of the money spent at £75m (81.5 %).
This included the cost of almost 5,000 PSNI officers and 3,600 from other forces drafted in from England, Scotland and Wales.
In terms of international media coverage, the 54-page report described it as "extensive and for the most part positive".
But, when it came to directly benefitting Fermanagh businesses, the report said: "For most the G8 summit had no impact."
It added: "Further, in the short term the proportion of businesses experiencing a positive impact appeared to be largely counterbalanced by those where the impact was negative.
"While around half of the accommodation sector had guests staying with them in connection to the G8 summit, they considered the impact on revenue to be relatively limited. This is because there was some displacement of other guests which meant bookings were either completely or partially lost.
"Official statistics support the views that the accommodation providers that there was no significant uplift in occupancy rates in the period around the G8 summit.
"However. there has been a strong uplift in guests from outside Northern Ireland staying in the south west during the last six months of 2013."
The report, called "An assessment of the importance to Northern Ireland of hosting the 2013 G8 summit", was commissioned by the Northern Ireland Executive "through the G8 co-ordinating group".
More than 600 delegates were estimated to have stayed in Northern Ireland during the summit along with 1,000 media.
The report said: "There was some leakage of spend to the Republic of Ireland where a number of the larger delegations were based."
