SHARES in Madame Tussauds owner Merlin soared on Friday as it accepted a £5.9 billion takeover offer, while London's top stocks finished the week on a cautiously optimistic note.

Merlin Entertainments said it had agreed to a bid from Lego's owners, a private equity giant and a Canadian pension fund, sending the firm's shares up by 54.1p, or 13.7 per cent, to 449.1p and making it the top riser on the FTSE 250.

The blue-chip index was in line with global markets as investors anticipated a meeting between the leaders of China and the US over the weekend.

Fiona Cincotta, senior market analyst at City Index, said: "Traders are looking optimistically towards Trump and Xi Jinping's bilateral meeting at the G20. The meeting will take place on Saturday morning local time, traders will react as the markets open on Sunday evening.

"The fact that equity markets are trading higher across the board gives a fairly clear indication that investors are optimistic of some progress. Historically the odds are onside for a truce between the two powers, if the last G20 is anything to go by."

The mood was similarly lifted on European markets, with the German Dax up 1.04% and French Cac 0.91% higher.
