Sarah Wollaston - obesity, not a sugary drinks tax, is regressive

The UK Parliament's Health Select Committee's recent report on childhood obesity says 1 in 5 children are obese by the time they leave school. The committee calls for legislation to turn the tide by taxing sugary drinks, a pre-watershed ban on junk food advertising, and investment in public health. We joined Sarah Wollaston, conservative MP for Totnes, and chair of the committee for lunch (thai chicken soup) to discuss their recommendations.
