Has the Prime Minister ever seen a bottle of water before?

It would appear not, from Dave's perplexed expression on his Cornish holiday.

The PM, famously a fan of 'chillaxing', is on his fourth vacation of the summer, after visiting Italy, Ibiza, and the remote Scottish island of Jura, where he revealed a bad back had prevented him from deer stalking.

Pictured on the beach with wife Samantha, the couple were dressed 'in complementary blue tones, with Mr Cameron opting for a navy polo shirt and matching shorts, while his wife wore a denim blouse teamed with beige chino shorts' the Press Association reported.

How did it stack up against his previous holiday fashion disasters? You decide:
