March 19 (Reuters) - London's FTSE 100 edged up on

Wednesday, supported by gains in precious metal miners and

energy shares, while investors monitored escalating tensions in

the Middle East.

The blue-chip FTSE 100 index rose 0.9% to 10,684.33

points by 1010 GMT, while the midcap FTSE 250 climbed

0.1%.

* The precious metal mining stocks jumped

2.8% to lead sectoral gains, with technical buying and

safe-haven demand ahead of next week's U.S. Federal Reserve

meeting pushing gold prices to a two-week high.

* Energy gained 1.4% after oil prices rose to

near six-week highs on mounting concerns that escalating

U.S.-Iran hostilities and threats by Yemen's the Iran-backed

Houthi militia will disrupt key supply routes.

* British inflation cooled more than expected last month as

a U.S.-Iran de-escalation reduced fuel prices, but the relief is

likely temporary for new Prime Minister Andy Burnham, who seeks

to ease living costs.

* "The economy feels sick and with stock prices high it

won't take much to tip the balance... We have to hope that the

new Chancellor has come in with a plan. He has some breathing

space, but to keep investors from cashing out and leaving the

Chancellor with even less room to manoeuvre, this will need to

be credible and implemented fast," said Nick Saunders, CEO of

online investment platform Webull UK.

* Among stocks, Segro ( SEGXF ) jumps 4.6% to the top of the

FTSE 100 after Prologis' submits final takeover proposal for the

Britain's warehouse landlord.

* J D Wetherspoon ( JDWPF ) fell 7.5% after the British pub

chain warned that annual earnings would likely miss expectations

due to weaker sales and rising costs.
