I have received a large sum of money from the sale of my business. In the next two weeks or so I will have to pay out money for fees, taxes etc. so I need easy (if not instant) access. Barclays suggest I put the money on the overnight money market at 4.7% Wouldn't I be better to open an instant access account with B/ham Midshires at 6.52% or another high interest account?

The best way is to employ a financial adviser to look after your finances. Overnight money market should be used only if you get advice from Barclays ... not suggested by them. It is not 100 % safe.
