The FTSE and UK will begin Friday with a hung parliament, casting a pall of uncertainty over Brexit negotiations and how they may take place.
PM Theresa May's hopes for a landslide victory by her Conservatives party fell well short, with reports about 6am stating it had obtained 316 seats.
Labour snapped up 265 seats, with the Scottish National Party grabbing 34 and the Lib Dems getting 13.
Plaid, Green and other parties nabbed 3, 1 and 18 seats respectively.
The markets had feared a hung parliament outcome. At about 6.02am, sterling was down 1.5% to $1.2762. It also fell 1.43% to €1.1386.
Sterling's Friday flop comes after its Brexit embarrassment in June last year, the ballot then having firmly divided the country along leave and remain battle lines.
