The FTSE 100 closed higher on Wednesday, halting a three-day losing streak as fears over a trade war between the US and China eased.
London's top flight closed up 0.3%, or 23.55 points, at 7,627.40.
David Madden, market analyst at CMC Markets, said: "Stock markets are broadly positive as investors are a little less fearful about a global trade war.
"Beijing softened its stance overnight, but there was a report recently that they will have a strong countermeasure against the tariffs imposed by the US."
Online grocer Ocado ended the best blue chip performer, up 52.7p at 1,001.5p after Peel Hunt reiterated its buy rating and nearly tripled its price target, saying it has the potential to become the "Microsoft of retail logistics".
The stock has surged in value since this year off the back of a flurry of high profile international deals.
Sky was also one of the high flyers, closing up 42p at 1,380p after Disney upped the ante for 21st Century Fox, making a 70.3 billion dollar (£53.3 billion) counterbid for its entertainment businesses following Comcast's 65 billion dollar (£49.2 billion) offer for the company.
The bid includes Fox's 39% stake in Sky.
"Sky shares are higher after Disney upped its offer for 21st Century Fox, and keep in mind that Comcast are also in the process of bidding for most of Fox's assets - which include a 39% stake in Sky," Mr Madden added.
At the other end of the FTSE 100, housebuilder Berkeley was rooted to the bottom of the index after warning that strong earnings growth is unlikely to last, with profits set to come in a third lower next year.
Berkeley said profits had peaked and will be "returning to more normal levels from 2018/19, when profits are anticipated to be around 30% lower".
Shares ended down 244p to 3,893p.

Sterling had a mixed day ahead of a crucial Brexit vote in the House of Commons, which saw the Government defeat an amendment tabled by Dominic Grieve over a "meaningful vote" for MPs on the UK's exit.
The pound ended the session up 0.2% against the US dollar at 1.319 and against the euro by the same figure at 1.138.
Lukman Otunuga, research analyst at FXTM, said: "The outlook for Sterling remains tilted to the downside, especially when factoring in how Brexit-related uncertainty and political risk may force the Bank of England to delay monetary policy normalization this summer."
The British currency will be in focus again on Thursday when the Bank releases its latest interest rate decision.
