Brexit concerns weigh on FTSE 100, Hut Group soars

The FTSE 100 slipped on Wednesday as fears of a disorderly exit for the UK from the European Union kept risk sentiment subdued, while shares of The Hut Group surged in the biggest UK initial public offering since 2013. The e-commerce firm rose 24.9% in its first day of trading.

The blue-chip FTSE 100 and the mid-cap FTSE 250 were down 0.1% and 0.2%, respectively, with banking stocks and insurers among the biggest decliners.
