It didn’t take long for the open-borders brigade to try and politicise the magnificent feat of British teenager Emma Raducanu in winning the US Open women’s singles.

Rather than just revelling in the general outbreak of joy in the country, or praising the astonishing maturity of Emma’s performance, the usual blue-tick suspects piled onto Twitter within minutes of her victory to argue, or imply, that the fact Emma was born in another country (she moved here from Canada aged two) proved that immigration in all its guises is always a good thing.
