UN headquarters | A third Stephen Moss? | Overstaying guests | Cutting cafe sign | Haircut patience | Pre-loved ridiculousness

Nesrine Malik rightly questions the effectiveness of the current United Nations (War, power games and impunity. I watched the farce that is the UN general assembly: what a tragedy, what a mess, 1 October). Why has there been so little outcry about Donald Trump’s blocking of visas for Palestinians and Sudanese (or any other accredited members) to attend the UN in New York? Despite the cost and upheaval, it is time to call Trump’s bluff and relocate the UN, preferably to Switzerland.

• Imagine my excitement to discover in your interview with Erasure (2 October) that Andy Bell’s partner is Stephen Moss! But which of the fabled Guardian doppelganger journalists could it be? Or, heaven forfend, might there be a third Stephen Moss?
