UK markets start the week in the red with politics and commodity volatility driving sentiment.
The FTSE 100 dips 43 points (0.7%) to 6,292 and the FTSE 250 loses 90 points, or 0.5% to 17,100.
Odey Asset Management, a shareholder in both Playtech and Plus500, previously opposed the deal saying it substantially undervalued Plus500.
The deal is being scrapped as it will not secure UK regulatory approval by the end of 2015, sending Playtech tumbling 10.8% to 759.5p and making it the biggest FTSE 350 loser.
Playtech says the termination increases the risk that its purchase of Ava Trade will also get cancelled.
Plus500 trades just 1.7% lower at 352p despite the cancellation of the deal amid heavy early trading in the stock.
