The London market lifted close to a 14-month high in afternoon trading, buoyed by gains in financial stocks. The FTSE 100 Index was 22.8 points higher at 6,832, after Standard Life stock hit its highest level since the UK's Brexit vote, following the insurer reporting an increase in assets under management. The FTSE 250 rose 44.3 points to 17,602.
Top flight shares are hovering at just below a high last reached in June 2015. The FTSE 100 index is up around 9% so far this year.
Standard Life said total assets under administration rose 6.7% to £328bn ($428bn) in the half year, helping shares rise 14.1p to 332.6p.
Worldpay, which provides platforms for merchants to accept payments by cards and other methods, said its underlying earnings rose 19% to £217.9m ($282.9 million) for the six months ended June 30.
The payment processer's statement was ahead of City forecasts, which saw shares rise 15.1p to 316.5p.
Trustnet Direct market analyst Tony Cross said: "Worldpay Group also updated the market this morning and this is another company benefitting off the back of the falling pound – news that has helped propel the stock to the top of the board."
