All eyes on Carrie Johnson in first role as UK first lady at G7 summit

Newlywed, 33, may be youngest spouse but her political nous should serve her well in keeping the plus-ones happy

Newly wed and with her new married name, Carrie Johnson takes on her first challenge as Britain's first lady when she hosts the partners of world leaders at next week's G7 summit.

At 33, the conservationist and erstwhile political PR will be the youngest spouse as she stands by the side of Boris Johnson, 56, at their first key event since their secret marriage on Saturday.
