His barrister Nick Cartmell said: "He is adamant he wasn't standing.

"He accepts he was high in his seat but wasn't standing and was in full control of the vehicle.
"It is a very, very small car.
"It would have been like the Big Friendly Giant in Noddy's car."
Elliott, of Aldwick Road, Scotswood, Newcastle, will be tried by a jury on January 23 next year.
Judge Edward Bindloss granted him unconditional bail in the meantime.
