Twists and turns

Jeremy Hunt, taking a group of EU foreign ministers around the maze at Chevening House in Kent, likened it to Brexit. It is not surprising if he finds the maze at Chevening difficult, because it was deliberately designed by the 2nd Earl of Stanhope, a mathematician, to be a greater challenge than garden mazes which preceded it. Most at the time had a simple rule: if you kept your hand on one hedge you would eventually reach the centre. This was known as a ‘simply connected’ maze. Chevening, however, was one of the first ‘multiply connected’ mazes, which don’t have a simple rule to find the centre.

Procreating royals

The Duchess of Sussex is expecting a baby ‘next spring’. How long does it take a royal couple to produce a child after the wedding?

Prince Charles and Diana, Princess of Wales
11 months
Prince Harry and the
Duchess of Sussex
10-12 months?
Prince Andrew and
Sarah Ferguson
2 years 1 month
Prince William and the
Duchess of Cambridge
2 years 3 months
Princess Royal and
Captain Mark Phillips
4 years 0 months
Prince Edward and the
Countess of Wessex
4 years 5 months


Carbon data

How is the UK getting on with reducing its carbon emissions? There are two ways to measure a country’s CO2 emissions — ‘territorial’ basis, which includes only those emissions within the country itself, and ‘consumption’ basis, which includes emissions spewed out around the globe in the cause of manufacturing goods and providing services for that country’s people.

Measurements in metric tons co2

Territorial basis / Consumption basis
560 / 654
564 / 727

416 / 596

So territorial emissions have fallen by 25% in 25 years but consumption emissions by only 9%. Source:
