Is the government really spending a billion pounds on the Jubilee, as some have claimed? We investigate some of the facts and figures around this week’s commemorations. We also ask why energy bills are becoming so high in the UK when we actually have plenty of gas, and we unpack the mystery of measuring fuel poverty. Plus after the Texas school shooting we investigate the statistics around gun deaths in the US.

And finally we hear about the joys and perplexities of imperial measures with Hannah Fry and Matt Parker.
