CORPORATE football fans shelling out thousands of pounds for executive packages at St James’ Park have been warned they face being kicked out of the ground following outbreaks of disorder.

Supporters paying up to £4,000 a game to watch Alan Pardew’s team have been issued with letters demanding they keep their guests in order during fixtures.

In the correspondence sent to the corporate customers in the ground’s executive boxes and lounges, club chiefs have said they will not tolerate unruly behaviour from guests who support the visiting team.

Last night Newcastle officials declined to comment when approached by The Journal, but it is understood trouble flared during Newcastle 3-0 defeat to Manchester United.

More than 20 Red Devils fans were ejected from the ground for a number of offences and it is believed seven were kicked out for sitting among the home supporters, which is a breach of ground rules.

In the official letter, Newcastle’s head of security Steve Storey writes: “I am writing to advise you that at recent matches this season there have been a number of incidents within the corporate areas involving guests who support the visiting team.”

Mr Storey urged clients to “be aware” they would be responsible for the actions of their guests following Newcastle’s fixture with Manchester United on October 7. Following Tom Cleverley’s 71st minute goal that effectively ended Newcastle’s hopes of a comeback, travelling supporters in the executive boxes erupted in celebration.

But it is understood their actions sparked complaints from fans in neighbouring boxes.

In his letter, Mr Storey states: “Newcastle United welcome guests from the opposing team at all times, however please be aware the client shall be responsible for the behaviour of its guests, whether they are home or away fans.

“Failure to do so may result in your guests being ejected from the stadium in accordance with the Stadium Ground Regulations. Thank you for your support in this matter.”

It comes just weeks after the club announced they could sue two streakers who landed the side with heavy fines from Uefa for their misbehaviour on the pitch.

The Premier League club could be charged as much as 17,000 euros – which amounts to around £13,000 – for two separate incidents during Europa League games at St James’ Park.

The first, against Greek side Atromitos, saw Steven Arkle, 21, from Kenton Road, Newcastle, run naked on to the pitch and hold up play for several minutes as he evaded stewards. Weeks later, against Bordeaux of France, John Parkinson, 35, from East Bawtry Road, Rotherham, South Yorkshire, ran on to the turf in front of thousands in the ground, and a global TV audience, wearing just an England shirt.

Both men – neither of whom have a season ticket or are an official club member – pleaded guilty to public order offences at Newcastle Magistrates’ Court.

Neither would accept football banning orders so they will be sentenced in mid-December.
