Parents at Leeds' Brodetsky Primary have got into a twist over yo-yos after the school allowed an outside company to promote them to pupils.
Brodetsky has received complaints over a motivational assembly programme, "The NED Show", run by American-based company All for Kidz and featuring yo-yo tricks.
There is no charge for the show but participating schools are asked to sell its stunt yo-yos, costing £5-£10, for five days afterwards.
Headmaster Jeremy Dunford said the assembly last Friday had been successful in promoting self-esteem and new learning skills.
