A drug which could help up to a million people in the UK who suffer from type 2 diabetes may soon be available on the NHS.

In final draft guidance, the National Institute for Health and Care Excellence (Nice) recommends the use of dapagliflozin for some people who suffer from the blood sugar condition.

The new drug, also known as forxiga, blocks the re-absorption of glucose in the kidneys and "promotes" excretion of excess glucose.

Manufacturers Bristol-Myers Squibb and AstraZeneca estimate that as many as one million patients could benefit from the drug.
