The organisers of the CLA Game Fair at Blenheim Palace are to hold talks with police and council leaders to try to ensure Friday's traffic chaos is not repeated.

More than 151,000 people attended the three-day event over the weekend but on Friday, there was gridlock on major roads around Oxford for much of the day as tens of thousands of drivers headed to Woodstock for the fair, run by the Country Land and Business Association (CLA).

As well as the huge volume of extra traffic, a car overturned on the A34 north of the Pear Tree interchange shortly before 8.30am, adding to the problems.

Organisers said there was no guarantee the event would return to Blenheim in four years' time, although there are hopes it will.

But David Hough, the game fair's director, promised a review of this year's event, including a thorough analysis of the traffic problems.

He added that there were 10,000 more visitors to the event on Saturday than on Friday, without any traffic congestion.

He said: "Game Fair staff and representatives of the West Oxfordshire Safety Advisory Group, which includes police and local authorities, will meet in October.

"Information will be gathered in advance of the meeting and there will be a thorough review by all parties.

"We had a record attendance of 151,000 and the people who attended the show, and the exhibitors, really enjoyed it.

"We would like to come back in 2012 - that's the current plan, and the last thing we want is to cause any inconvenience."

But many people were furious their plans for Friday were disrupted because of the fair.

Peter Barratt said: "I had to cancel a visit to a friend in Brecon, because it took me two hours to get from my flat in Cherwell Drive to the roundabout at the end of the Banbury Road.

"Seeing no sign of any clearing of the traffic, I turned round and came home. The appalling gridlock must have caused thousands of similar disappointments.

"The lesson to be learned from this shambles is that Woodstock isn't a suitable venue for such a huge event."

Ian Hudspeth, the county council's cabinet member for transport, said: "I will be attending the meeting, together with representatives of the police and West Oxfordshire District Council, to look at what happened and see what could be done better next time."

Organisers believe attendance was boosted after last year's event, at Harewood House, in Yorkshire, was cancelled due to flooding.

The last time the fair came to Blenheim, in 2004, 137,500 people came through the gates.

Sue Brothers, a spokesman for the South Eastern Gun Dog Society, said she attended the 2006 fair at Broadlands, near Romsey, in Hampshire, and added: "The access off the M3 is pretty good and I don't recall any major traffic hold-ups."

Next year's event is at Belvoir Castle, in Leicestershire.
