Sorry, but I'm with the official RCFC line on this. I wouldn't want to be giving away free tickets to away fans for ICT games. There's probably a legal argument in there too about supplying tickets to the away end and the visiting team having responsibility for their fans behaviour.
I'm glad that ICT fc's opinion differs from yours, they do not see the harm in letting the winner of a competition etc, sitting in the away end if they choose to do so.
As for trading standards (subject to availability) told on both occasions that seats were not available for the away support.
Would maybe try anyway as they are available (TS ) If not does your neice know any county fans to buy them and use the money to buy away end ones ? Sounds like they are being awkward as the home club are responsible for all fans.
