* FTSE 100 down 0.1%, FTSE 250 falls 0.09%

* Energy stocks gain as oil prices extend rally

* Rio Tinto rises after stronger iron ore sales

* Personal goods lead sectoral gains

July 15 (Reuters) - London's FTSE 100 slipped on Wednesday

as investors remained cautious over escalating tensions in the

Middle East, while losses in precious metal miners outweighed

gains in energy shares as oil prices rose.

The blue-chip FTSE 100 index fell 0.1% to 10,515.73

points by 1013 GMT, while the midcap FTSE 250 slipped

0.09%.

* Precious metals miners declined 2.3%,

making them the worst-performing sector, with Fresnillo

and Endeavour Mining ( EDVMF ) falling 2.8% and 2%, respectively,

among the top losers on the benchmark index.

* On the flip side, energy stocks rose 0.3%

as oil prices climbed around 2% after U.S. President Donald

Trump reimposed a naval blockade on all Iranian ports and Iran's

Islamic Revolutionary Guard Corps threatened to close "all other

export corridors that benefit the U.S. and its allies".

* The personal goods index rose 2.4% to lead

sectoral gains, buoyed by a 4.8% jump in Watches of Switzerland

Group ( WOSGF ) after brokerages Barclays and UBS lifted target

price on the stock.

* The OECD said Britain must maintain fiscal discipline,

tackle rising pension costs and address high energy prices to

boost economic growth, underscoring the challenges facing Andy

Burnham, who is set to become prime minister next week.

* On Tuesday, Britain's FTSE 100 closed higher as bank

stocks led gains after strong earnings from major U.S. lenders

kicked off the reporting season, while a softer-than-expected

U.S. inflation reading fuelled expectations of a delay in

interest rate cuts.

* Among individual stocks, Rio Tinto rose 1.1% after

the mining major reported better-than-expected second-quarter

iron ore sales, supported by strong operational performance.

* Shares of B&M fell 6.9% after the discount

retailer reported a 2.3% decline in first-quarter like-for-like

sales in its core UK market, as a slow start to the gardening

season weighed on trading, though growth in France helped lift

group revenue.

* Barratt Redrow ( BTDPF ) rose 3.3% after the housebuilder

said it would return £400 million ($536 million) to shareholders

through share buybacks instead of dividends.
