Opinion | John Kerry’s British Election Meddling

Remember American politicians who profess to be aghast at foreign interference in domestic U.S. politics? Apparently there’s an exception when John Kerry is interfering in another country’s election. Witness the kerfuffle the U.S. climate envoy caused in the United Kingdom this weekend with his intervention in the Conservative Party leadership race.

Climate policy is an issue in the contest to succeed Boris Johnson as Tory leader and British Prime Minister after Mr. Johnson’s green ambitions wreaked so much economic damage. Green levies and hostility to domestic oil-and-gas production contributed to a 54% rise in household energy costs in April, with another 40% increase expected in October. One of Mr. Johnson’s worst fumbles was a plan to force households to abandon the natural-gas boilers they use for hot water and central heating, and to spend thousands of dollars installing heat pumps instead.
