In my not-so-professional opinion as a Masters in Finance student (and CFA Level 2 candidate), 
Index. Not any index fund, but a broad-based one. An index fund is a fund which simply replicates an index. You want to buy an index fund that replicates the entire stock market...if possible the entire worlds' stock market. In Britain I'm sure there is an index fund which replicates the FTSE. You can buy that, but it still is only exposed to Britain.
In the USA their is an exchange-traded fund by the ticker VT that replicates the entire worlds' stock market (okay...98% of it). Buy something in Britain like it if you want equity exposure.
This is important: As much as I like Uncle Erik and the crew, I must warn you to guard yourself against ALL forecasts. Even well meaning ones. You must never, ever, try to predict where the market is going. It's a fools errand. No one can do it. Even Warren Buffett (or especially Warren Buffett) would warn you against it. There are many Noble prize winners who would agree. The finance academy feels the same way about "Market Timing" as Uncle Erik feels about cables.
(ie, it's voodoo). Eugene Fama frequently refers to CNBC and the like as "investment p*rn."
Once you get some real 'coin, you're going to want to set up an investment policy you will stick with no matter how good or bad things get. And for that I present you with the Head-Fi of investment: Bogleheads.org
