London's FTSE 100 recorded its best day in over two weeks on Thursday, led by gains in heavyweight mining and bank stocks, while Workspace Group surged as demand for its office spaces recovered.

The blue-chip FTSE 100 gained 1.2%, with miners Glencore, Anglo-American and Rio Tinto among the top boosts. Industrial and precious metal miners added 2% each on higher metal prices. The FTSE 100 has gained about 9.5% so far this year and the mid-cap index is up nearly 10% amid re-opening optimism and accommodative central bank policies.

However, a recent rise in inflation on the back of surging oil and gas prices has weighed on the UK's benchmark indexes as investors now bet on a sooner-than-expected pullback of easy monetary policies.

"Investors are now very much aware we are entering a period where we are going to have continued inflation and it is not going to be ridiculously transitory either," said Danni Hewson, an analyst at AJ Bell.

"But there is a lot of hope still that it will not last beyond a few months."
