LONDON, June 12 (Reuters) - Britain is ready to

implement its side of a tariff deal with the United States and

is hopeful for a proclamation from U.S. President Donald Trump

to put the agreement into effect in the coming days, trade

minister Jonathan Reynolds said on Thursday.

British Prime Minister Keir Starmer and Trump on May 8 agreed to

reduce tariffs on UK imports of cars and steel to the U.S., with

Britain agreeing to lower tariffs on beef and ethanol, but

implementation of the deal has been delayed.

Reynolds met U.S. Commerce Secretary Howard Lutnick on

Tuesday and discussed the implementation of the deal. Asked on

Thursday if there would be an update by the end of the week,

Reynolds said he was "very hopeful".

"We're ready to go, and as soon as the president and the

White House are ready to go on their side, we'll implement (our)

part of the deal," Reynolds told reporters.

Reynolds said he would issue a government order known as a

statutory instrument to implement the changes to reciprocal

tariffs. Officials said that the update on implementation was

likely to come early next week.

One of the details to be ironed out before the deal can be

implemented is steel quotas. Reynolds added that he wanted to

make sure the tariff reductions applied to every bit of the UK

steel industry, as the U.S. finalises quotas that will place

supply chain requirements on British steel exports to the United

States.

The bioethanol industry has warned its future is under threat,

with Associated British Foods ( ASBFF ) deciding on the fate of a

plant later this month. Reynolds acknowledged the deal could

increase competition but said the industry was already

struggling.

"We are very sensitive to the ethanol issue... (but) they're

losing a lot of money already," Reynolds said, adding regulatory

tweaks could help, but that for financial support: "any

intervention I make has to be a clear route to profitability."

"So there are much wider issues for these partners than just

the U.S. trade deal."
