The market failed to keep up the optimism it had shown late last week as China signalled it might take longer than hoped to wrap up the first part of a trade deal with the US.

State-owned newspaper China Daily wrote on Sunday those hoping for a trade deal should not count their chickens before they hatch.

"While the negotiations do appear to have produced a fundamental understanding on the key issues and the broader benefits of friendly relations, the Champagne should probably be kept on ice, at least until the two presidents put pen to paper," the paper wrote.

David Madden, an analyst at CMC Markets, said that traders had been caught off guard by the signalling from China.

"The update from Beijing has resurfaced some trade concerns, so dealers are trimming their positions in equities," he said.

The FTSE 100 closed down 33.63 points to end the day on 7,213.45. Meanwhile the FTSE 250 dropped 111.81 points to 19,929.90.

Sterling, meanwhile, was down 0.25% against the dollar to 1.2588. The currency settled after a massive 4% rise late last week on news that Prime Minister Boris Johnson and Irish Taoiseach Leo Varadkar had found common ground on Brexit.

But the news was not as positive over the weekend, said Connor Campbell, an analyst at Spreadex.

"Given the lack of progress over the weekend - the bloc said Boris Johnson needs to move 'further and faster' if he is to secure a deal in time - and the sheer exuberance seen across Thursday and Friday, it wouldn't have been a surprise to see sterling suffer a severe comedown," he said.

Germany's Dax was down 0.2% on the day, while the French Cac index fell 0.4%. The Dow Jones opened flat.
