Jan 22 (Reuters) - London's FTSE 100 recorded its longest
losing streak since early December as a strengthening in
sterling triggered by strong manufacturing sentiment data
weighed on dollar earners, while travel group TUI slid on more
Boeing woes.

The main index reversed earlier gains to decline
0.5% on its third consecutive day in the red.

Homebuilder Berkeley limited losses on the index,
jumping 5.4% to a record high after plans to return 450 million
pounds more to shareholders. An index of housebuilders
scaled over a two-year high on the news.

The FTSE 250 added 0.1%, buoyed by a stronger local
currency.

The pound scaling a five-week high against the euro came as
bets of a cut to the UK interest rate declined after the
Confederation of British Industry reported a pick-up in
manufacturers' sentiment.

That dragged on bluechip exporters including GlaxoSmithKline
, HSBC and British American Tobacco.

A standout faller was TUI, whose London-listed
shares slipped nearly 6% to their lowest since September after
Boeing warned of further delay in returning its grounded
737 MAX airliner to service.

The FTSE 100 missed out as world shares held firm after
Chinese authorities ramped up efforts to control the outbreak of
the coronavirus, which is being likened to the 2002-2003 spread
of Severe Acute Respiratory Syndrome (SARS) and has already led
to nine deaths.

Sage Group outperformed the bourse with a 4% rise as
the software provider reported higher quarterly revenue and
affirmed its annual forecast.

But Burberry slid 5% despite a solid performance
through the Christmas quarter.

"The reminder of how closely the company's fortunes are tied
to China may have provoked some nervousness given the deadly
virus which is currently afflicting the country," AJ Bell
investment director Russ Mould said.

He also suggested that there could be a hint of
profit-taking, given the recent rally in shares.

Further driving the index lower was a dip in Shell
and BP as oil prices weakened, and miner Antofagasta
which fell 4.6% after its copper production was hit by
civil unrest in Chile.

Small-cap fashion retailer Ted Baker sank as much as
10% after it more than doubled its preliminary estimate of an
overstatement in inventory.

A combination of multiple profit warnings, subdued consumer
sentiment and a slew of management changes after allegations of
misconduct against founder Ray Kelvin had knocked more than 70%
off the stock's value last year.
