May 14 (Reuters) - British shares surged on Tuesday as
investors grew optimistic about a U.S.-China trade deal after
U.S. President Donald Trump vowed it would happen soon, while
demand for vegan sausage rolls propelled baker Greggs to a
record high.
The FTSE 100 .FTSE jumped 1.1%, its biggest one-day rise
since early February, while the FTSE 250 .FTMC climbed 1.3% on
its best day in more than four months.
Offering respite to a market that has been roiled by
tit-for-tat tariffs in the last week, Trump said a trade deal
with China would be reached soon, despite fears about a
protracted trade battle.
"There appears to be a degree of calculation going on here
in that investors appear to be banking on any increased tariffs
being in place for only a short period of time, with a deal
being concluded soon after," CMC Markets analyst Michael Hewson
said.
"Time will tell whether that belief is prescient or naïve."
Oil majors Shell RDSa.L and BP BP.L provided the biggest
boosts on the main index as crude prices surged after Saudi
Arabia said explosive-laden drones attacked facilities belonging
to state oil company Aramco. O/R
Asia-facing financial heavyweights and miners .FTNMX1770
rebounded after steep losses in the previous sessions.
An earnings-laden day also saw support services group DCC
DCC.L among the top gainers with a 3.6% rise, after it posted
annual results and guided to another year of profit growth.
A sour spot on the index was telecoms giant Vodafone
VOD.L , which dropped 3.7% to its lowest in a decade after it
slashed its dividend to secure enough firepower to build 5G
networks and complete its acquisition of Liberty Global assets.

Property developer Land Securities LAND.L also lost 1.4%
after it reported a wider loss due to a steep decline in the
value of its assets on account of a string of collapses on
Britain's shopping streets. Among mid-caps, baker Greggs GRG.L surged more than 15% to
an all-time high after it said the popularity of its vegan
sausage rolls had continued to grow, leading it to hike its 2019
profit forecast for the second time this year. Pub owner EI Group EIGE.L jumped 6.5% after it reported a
rise in half-year earnings and said a late Easter had given a
good start to its second half. But Renishaw RSW.L skidded 6.4% to a near two-year low
after the engineering group cut its annual profit target for the
second time this year.
