Antibiotic resistance has caused a fall in life expectancy for the first time, the Office for National Statistics has said.

Life expectancy in future years has been revised down after the statistics authority said that "less optimistic views" about the future had to be taken into account.

Opinions on "improvements in medical science" had declined, it said, and fears of the "re-emergence of existing diseases and increases in anti-microbial resistance" meant people would not live as long as was previously expected.

The ONS uses predictions about how medicine and science will improve to model how life expectancy will change.

Under the projection made in 2010, a baby girl born in 2016 could expect to live 83.7 years. This has now been revised down to 82.9.

Life expectancy for babies born in 2060, the latest year which appears in both models, is now two years shorter than it was in the 2010 data.

Baby girls born in that year were previously expected to live to 90.1 - this has now fallen to 88.3.

Baby boys are also set to live less long, with children born in 2016 expected to live to 79.2, instead of 79.9, and those born in 2060 expected to live to 85.7 instead of 86.8.
