SIR - The Tories have invented the ultimate cloaking device, one that US military stealth technology would be envious of. Is it some light bending invisibility technology? No it’s Brexit.

Never has a party in political power had such a long list of things that they are performing bad at. Grenfell, hostile environment, crime, universal credit, homelessness, slow economic recovery, Windrush, railways, energy monopolies, inequality, in work poverty and much more.

Any other party would be roasted if they rated bad on just two or three of the above list but since David Cameron powered up his Brexit device in 2016, all the above became invisible. The Philadelphia experiment had nothing on this.
