It was a bolt from the red, white and blue. A few weeks ago the youngest daughter of Thailand’s ageing king posted several photographs of herself on social media. One of them showed her with hair braids of red, blue and white; another of her wearing a similarly-striped bracelet. These are the colours of Thailand’s national flag, but they have also come to be associated with the anti-government protesters who have rocked the country as they seek to oust Prime Minister Yingluck Shinawatra.
