(Sharecast News) - London's FTSE 100 was up 0.4% at 8,265.20 in afternoon trade on Wednesday.

Flutter Entertainment surged to the top of the index, having said late on Tuesday that it was lifting full-year guidance after a better-than-expected second-quarter performance.

The company now expects US revenue of between $6.05bn and $6.35bn and adjusted EBITDA of $680m to $800m. This is up from previous guidance of $5.8bn to $6.2bn revenue and adjusted EBITDA of $635m to $785m.

Revenue outside the US is expected to be between $7.85bn and $8.15bn, while adjusted EBITDA is set to be $1.69bn to $1.85bn. This is up from previous guidance of $7.65bn to $8.05bn and $1.63bn to $1.83bn, respectively.

Flutter was also in focus after Playtech confirmed it was in talks with the company about the possible sale of its Italian business, Snaitech.

Ladbrokes owner Entain also gained.

Housebuilders Persimmon, Berkeley, Taylor Wimpey and Barratt all rose after a smaller-than-expected rise in UK consumer price inflation boosted rate cut hopes.
