* June, Q2 UK GDP data due on Thursday

* Vistry falls on report Allianz Trade reducing cover

* Plus500 climbs after rise in half-year core profit

Aug 10 (Reuters) - London's stock indexes were subdued on

Monday, pausing after last week's gains as investors focussed on

earnings reports and upcoming economic data for clues on the

health of the British economy.

The blue-chip FTSE 100 fell 0.2% to 10,874.64 points

by 1020 GMT, while the midcap FTSE 250 added 0.1% to

24,880.50 points. Both indexes notched their fourth consecutive

week of gains on Friday.

* Upbeat earnings reports and expectations of a U.S.-Iran

peace agreement have underpinned British stocks lately.

* Oil prices edged higher as optimism over talks to reopen

the Strait of Hormuz was tempered by Iran's insistence that the

United States must satisfy several demands before the waterway

could reopen.

* Data on Thursday is expected to show the UK economy grew

1.1% on an annualised basis in the second quarter, possibly

helped by lower energy prices. British retail sales were

unexpectedly strong in June, helped by spending related to warm

weather and the World Cup.

* Britain's labour market showed tentative signs of

stabilisation in July, as recruiters stopped shedding permanent

staff, according to a survey that also showed a faster rise in

starting salaries.

* Among single stocks, affordable homebuilder Vistry

slid 7.5% after the Financial Times reported that

credit insurer Allianz Trade was reducing the cover it extends

to Vistry's suppliers by up to 70%, a move that could exacerbate

a cash flow squeeze.

* Mining giant Glencore ( GLCNF ) climbed 2.2% after Barclays

raised its price target to 650 pence from 635 pence following

strong results last week.

* Plus500 climbed 5.9% after the trading platform

reported a rise in half-year core profit, aided by higher

trading activity.
