June 9 (Reuters) - Australian shares edged up on Friday as investors awaited final results of the United Kingdom's tight elections that could throw British politics into turmoil.
The S&P/ASX 200 index was up 0.2 percent, 8.803 points to 5,685.4 by 0300 GMT, and on track to post its first weekly loss in three weeks.
An updated BBC forecast predicted Prime Minister Theresa May's Conservatives would win 318 of the 650 House of Commons seats, eight short of a majority, while the left-wing opposition Labour Party would take 267 - producing a "hung parliament" and potential deadlock.
"It's clear that the unexpected result in the UK election (poll) this morning has played some part in investor thinking," said Michael McCarthy, chief market strategist at CMC Markets.
"The potential for a hard Brexit has receded and although globally this is unlikely to have a major impact, it is introducing a bit of caution to trading today. Trading volumes are also low as we're heading into a holiday weekend."
Australia market will be closed on Monday for a public holiday and will resume trading on Tuesday.
