LONDON, Sept 30 British Prime Minister Theresa
May will set out her vision of a successful Brexit on Sunday as
investors raise growing concern that the world's fifth largest
economy could face upheaval from a disorderly exit from the
The June 23 Brexit vote took many investors and chief
executives by surprise, triggering the deepest political and
financial turmoil in Britain since World War Two and the biggest
ever one-day fall in sterling against the dollar.
May's government has tried to reassure manufacturers and
banks that Britain is open for business and that it will take
their views into account during the country's negotiations on
new trade relations with the EU.
In a speech to open the annual conference of the ruling
Conservative Party on Sunday, May will give her first big speech
on Brexit since winning Britain's top job on July 13.
"The Prime Minister has been clear that we're going to get
the best possible deal for Britain and for business," a
spokeswoman for May said. "There are opportunities presented by
Brexit, and we're going to grasp them and make a success of it."
After May's speech on "Global Britain: Making a Success of
Brexit", Foreign Secretary Boris Johnson and May's Brexit
minister, David Davis, will speak on the subject.
May, who quietly argued that Britain should stay in the EU
during the referendum campaign, has repeatedly said since the
vote that "Brexit means Brexit" but that she will not trigger
the formal EU divorce process before the end of the year.
Despite warnings before the vote that Brexit would shatter
economic confidence, some positive economic data and SoftBank's
$32 billion takeover of Britain's technology company ARM have
stoked the perception that Britain could prosper outside the EU.
But the economic data is mixed, sterling is trading 40 U.S.
cents lower than the six-year highs it reached in mid-2014 and
some investors have raised concerns that their businesses could
be hurt, especially by a so called "hard Brexit".
Under a "hard Brexit", Britain would abandon the EU's
customs union, give up on seeking preferential access to the
single market and impose controls on EU immigration to Britain.
Nissan Chief Executive Carlos Ghosn cautioned that
he could scrap new investment in Britain's largest car plant
unless Britain pledged to pay compensation for any tax barriers
resulting from Brexit.
Jaguar Land Rover will "realign its thinking" on
investment if Nissan gets a Brexit compensation deal and other
automakers would need a level playing field, the head of
Britain's biggest carmaker said.
"There will clearly be commentary from a variety of sources
as we move forward, but we're not going to give a running
commentary ourselves - nor speculate on outcomes of negotiations
that haven't happened yet," May's spokeswoman said.
JPMorgan said in a note to clients that it would be a
surprise if May did not use her appearances at the Conservative
Party conference to give some guidance on her views of Brexit.
"In the eyes of many observers, the absence of detail on the
approach the UK will take to Brexit is creating a vacuum which
"hard Brexit" is starting to fill," JPMorgan said.
But May, who turns 60 on Saturday, has to balance an array
of views on Brexit, not least from many members in her own party
who are pushing for a clean break with the EU.
