LONDON (AP) — Britain's treasury chief says he expects America's next president to be a woman. Guess who?

In an unusual diplomatic departure, Chancellor of the Exchequer George Osborne offered his coy take Sunday on the race between leading Democratic Party candidate Hillary Clinton and the Republicans' sole campaign survivor, Donald Trump.

"We look forward to working with whoever the next president is, whoever she may be," Osborne, an ally of Prime Minister David Cameron, told the broadcaster ITV.

Conservative Party leader Cameron has repeatedly criticized Trump's anti-immigrant rhetoric. In December he called Trump's idea of banning Muslim travelers from U.S. soil "divisive, stupid and wrong."

Obsorne described Trump as part of "an odd collection" of extremists who want Britain to leave the European Union. Britain votes on the issue June 23.
