Coventry Building Society ISA, fixed for 4 years - beats Santander's 3%, cos this is tax free. At the mo you can only invest £5940, but after 1st July, this increases to £15 000.
If you want a real punt, shove a grand in "Oxus Gold" shares .... google "Oxus Gold arbitration" and all will be explained .... remember with risk, comes reward and these shares will either be worthless after the arbitration, or they going to be worth a lot more (5x .... poss even more).
.... sorry, forgot to add - Coventry BS ISA, fixed for 4 years - rate is 2.75% ... which beats Santander's rate of 3%, 'cos after tax, the equivalent rate is 2.4% at best ...... less if you're a higher rate tax payer.
