There are some pretty grim ones available (Diamond White is a particularly foul example) but hunt around a bit and you can uncover some corkers. The drinks section in Waitrose makes a fine start.
Ahh...Diamond White! Reminds me of the summer of '92 when I was 16 and spent 3 weeks in England visiting relatives. It was my first time in pubs, and I mostly drank Diamond White (Ice, I think?) and shandy's as I hadn't developed a taste for beer yet.
