More than a quarter of Wales' four and five-year-olds are overweight - with more than one in 10 classed as obese, say public health officials.

Merthyr Tydfil tops the league for weight issues in young children, with 34% regarded as overweight. Public Health Wales looked at the Body Mass Index (BMI) of just over 1,000 children starting primary school - with a BMI over 25 considered unhealthy.

Across Wales, 26% were over that BMI - while in England it was just 22%.

The average figures for Wales are also higher than the worst region of England - which is the north-east, where 24% of four and five-year-olds have slipped into the overweight BMI zone.
