(Updates after market close)

Nov 13 (Reuters) - London's FTSE 100 closed lower on

Thursday after a three-day run of record highs, weighed down by

financial shares as investors assessed disappointing

third-quarter economic growth data.

The blue-chip index ended 1% down, marking its worst

performance since April 9, when global markets were rattled by

U.S. President Donald Trump's tariff announcements.

The mid-cap FTSE 250 also dipped 0.6%.

The investment banks & brokerages sub index

extended declines from the morning and fell 7.8%.

3i Group ( TGOPF ) slumped 17.4% in its worst day on record

after the investment firm expressed caution about deploying

capital, saying that the transaction market and broader

environment will likely remain challenging.

The energy sector dropped 1.3% as investors

weighed concerns about global oversupply, even as oil prices

ticked up.

On the data front, Britain's economic performance showed

minimal momentum in the third quarter, with growth hampered by a

cyberattack on Jaguar Land Rover in September.

Sterling briefly touched a session low following the

data release before recovering to trade 0.5% higher.

Global markets remained focused on the flow of economic data

from the U.S. after President Trump signed legislation ending

the country's longest government shutdown. The 43-day data

blackout left both the Federal Reserve and traders uncertain

about labour market conditions and inflation trends.

Back in the UK, life insurers fell 2.4%, as

Aviva dropped nearly 6.2% after the insurer's new

financial targets failed to impress investors.

Rolls-Royce dropped 2.8%, even as the aero-engineering firm

said it was confident on its full-year forecasts despite supply

chain disruption.

Burberry ( BBRYF ) shares reversed course to end 2% lower

after hitting their highest since July 29 on the news that the

luxury brand had posted its first quarter of growth in two

years.

Precious metal miners rose 4.5%, easing

from an earlier 8.3% surge in the day, as gold retreated after

touching its highest level in more than three weeks.

Wizz Air's ( WZZAF ) shares climbed 6.7% after the airline

reported strong first-half operating profit.
