Sir – I am a junior doctor working at the Churchill Hospital. The Government has just announced it may not implement a new law to scrap cigarette vending machines and tobacco displays in shops.

We all know that vending machines are an easy source of cigarettes for children and that they are encouraged to smoke through slick marketing in tobacco displays.

With 40 per cent of adult smokers, or ex-smokers, starting smoking before they were 16, it’s clear we need to do much more to stop our children taking up this deadly habit.

That’s why I, along with thousands of others, am supporting the British Heart Foundation’s campaign to ensure the Government implements this law to protect our children from the dangers of smoking.
