Role model Raducanu

sir – Emma Raducanu has achieved through her victory at the US Open tennis tournament one of the most stunning personal sporting triumphs in living memory.

That she did so with such authority, calm, decisiveness and focus at a mere 18 years of age is quite breathtaking.

Her generosity to her opponents and modesty in winning are object lessons in how to behave in all walks of life. Kim Potter

sir – A thousand thanks to Channel 4 for allowing me, and others like me who only have Freeview, to watch this amazing tennis match – the most exciting I have ever seen.
