Of course, Britain is now in unknown, volatile territory. Brexit strains, combined with a working majority of just 16, could force her to seek a personal mandate from voters at an early election, or even bring down her premiership. At times the year will feel like a long series of arm-wrestles between the legislature and the executive. But Mrs May is cautious and, with neither Labour nor the UK Independence Party in a good state, will probably resist the temptation to cash in on her soaring poll leads. Indeed, these should help her keep a lid on impatience and dissent in her party.
What does the number 16 imply? Does that mean the party has half of the seats and 16 more?
