The FTSE 100 outperformed European peers on Thursday supported by gains in engineering stocks which helped offset weak miners.
The FTSE 100 closed up 56.32 points, 0.5%, at 10,572.24. The FTSE 250 ended up 253.44 points, 1.1%, at 23,715.83, and the AIM All-Share rose 0.44 of a point, 0.1%, at 766.18.
Sterling faded into the close after earlier hitting its highest level in a year against the dollar amid growing expectations that Home Secretary Shabana Mahmood will become chancellor under the incoming government led by Andy Burnham.
Ms Mahmood has emerged as the frontrunner to replace Rachel Reeves at the Treasury when Mr Burnham is expected to enter Downing Street on Monday, after weeks of speculation over his Cabinet appointments.
Energy Secretary Ed Miliband had previously been viewed as the leading contender for the role but is considered less favourably by financial markets amid concerns he would be less fiscally disciplined.
Meanwhile, the International Monetary Fund is urging Mr Burnham’s incoming government to avoid increasing public spending in the face of pressures such as rising household energy bills.
The pound traded at 1.3483 dollars on Thursday afternoon, little changed from 1.3486 on Wednesday. It had earlier traded as high as 1.3558.
Against the euro, sterling eased to 1.1784 euro from 1.1791 on Wednesday.
Sterling had risen sharply late on Wednesday as the first reports that Ms Mahmood might get the keys to number 11 Downing Street started to emerge.
Kathleen Brooks, research director at XTB, said the pound’s positive reaction tells us two things about Mr Burnham’s government.
“Firstly, the market trusts Mahmood to take a sensible approach to economic policy, and to tackle the hard questions of welfare spending. Secondly, Burnham is willing to have those to the right of the Labour party in his cabinet in key economic roles,” she said.
Investors also weighed figures showing the UK economy returned to modest growth in May, although the recovery remained subdued as the conflict in Iran continued to weigh on activity through higher prices and supply chain disruption.
According to the Office for National Statistics, gross domestic product rose 0.1% in May after contracting 0.1% in April, matching market expectations. A 0.3% expansion in the services sector offset declines of 0.5% in production and 0.8% in construction.
Over the three months to May, GDP grew 0.7%, easing slightly from an upwardly revised 0.8% increase in the three months to April.
Deutsche Bank’s chief UK economist Sanjay Raja expects momentum to dampen a bit as the year progresses.
The Iran “energy squeeze will eventually catch up with households and businesses, constraining spending and investment”, while lingering geopolitical uncertainty around the Strait of Hormuz “won’t help either”, he said.

“This all makes one wonder what US tech corporations will have to come up with to get investors genuinely excited again,” said market analyst David Morrison at Trade Nation.
