Turkish President Recep Tayyip Erdogan says he believes Turkish-British ties will flourish under Boris Johnson's term as prime minister.

In a message posted on Twitter Tuesday, Erdogan congratulated Johnson who won the campaign for Britain's Conservative Party leadership and is set to replace Theresa May as prime minister.

Erdogan wished Johnson success in his new job and added: "I believe that the Turkey-United Kingdom relations will flourish even more during this new era."

Johnson, who has part Turkish ancestry, received a warm welcome in Turkey in 2016 when he visited as foreign secretary despite the fact that he had based his Brexit campaign on the possibility of Turkey joining the EU and millions of Turks entering Britain. He has also composed an offensive poem about Erdogan.

European Commission President-elect Ursula von der Leyen has congratulated Boris Johnson, the Brexit-hardliner soon to become Britain's next prime minister.

Von der Leyen said Tuesday she was looking forward to a good working relationship with Johnson following his victory in the Conservative Party leadership battle.

With Britain scheduled to leave the European Union on Oct. 31, von der Leyen says, "We have the duty to deliver something which is good for the people of Europe and the United Kingdom."

French President Emmanuel Macron, hosting von der Leyen on her first visit to an EU country since her recent election to replace Jean-Claude Juncker on Nov. 1 as head of the EU's executive commission, said he wants to work "as quickly as possible" with Johnson, not just on European issues but on Iran and international security, subjects in which France is closely linked to Britain and Germany.

Iran's foreign minister has congratulated Boris Johnson on becoming Britain's next prime minister, following Johnson's victory in the Conservative Party's leadership vote.

Mohammad Javad Zarif tweeted: "I congratulate my former counterpart."

Zarif says Iran isn't seeking confrontation amid the tanker crisis in the Persian Gulf but that it has 1,500 miles (2,414 kilometers) of coastline. "These are our waters & we will protect them."

Iranian officials have suggested a British-flagged tanker was seized last week in response to Britain's role in seizing an Iranian oil tanker two weeks earlier off the coast of Gibraltar, a British overseas territory located on the southern tip of Spain.

Zarif on Tuesday also blamed Theresa May's government for the seizure of the Iranian tanker, describing it as "piracy, pure & simple."

British business groups are urging new Conservative Party leader Boris Johnson to take immediate action to secure a deal to leave the European Union that signals the country is open to enterprise.

Carolyn Fairbairn, head of the Confederation of British Industry, says Johnson has "no time to waste" in his first 100 days and warned him not to "underestimate the benefits" of a good Brexit deal. She says businesses need a "Brexit deal that unlocks confidence."

The British Chambers of Commerce warned Johnson to avoid a "messy, disorderly Brexit" by the Halloween deadline while Edwin Morgan, the interim director-general of the Institute of Directors, says it is crucial that Johnson "recognizes that this is a daunting time for many firms, and is prepared to back them."

Morgan says "a no deal Brexit would only add to the uncertainty and distract from these challenges, but avoiding a disorderly exit will enable the country to focus on them and move forward to everyone's benefit."

Germany's main industry lobby group says businesses need to see "implementable decisions" from Boris Johnson's new U.K. government and says any threats from London of a "no-deal" Brexit will backfire.

Joachim Lang, the chief executive of the Federation of German Industries, said in a statement that the withdrawal agreement that British lawmakers have rejected three times stands for "as little friction as possible" in trade and other issues and must not be renegotiated.

He said Tuesday that "business now urgently needs a government in the United Kingdom that makes implementable decisions. Threats from London to leave the EU in a disorderly way are harmful and will come back like a boomerang. They strengthen the damage to business that has already been done."

Johnson has vowed to leave the EU by Oct. 31 with or without a deal.

Trump tweeted: "Congratulations to Boris Johnson on becoming the new Prime Minister of the United Kingdom. He will be great!"

The president had endorsed Johnson to succeed May. Trump has been very critical of May's inability to achieve a Brexit deal and has said Johnson will do a better job.

Outgoing UK Prime Minister Theresa May has pledged to give "full support" to her successor, Boris Johnson.

May tweeted her congratulations to Johnson after he was elected Tuesday as the new Conservative Party leader.

May plans to remain in Parliament. She told Johnson he would have "my full support from the back benches."

Michel Barnier, the European Union's chief Brexit negotiator, says he looks forward "to working constructively" with Boris Johnson, who has been elected leader of Britain's Conservative Party and will become prime minister on Wednesday.

Barnier said he's looking to push through the ratification of the withdrawal agreement negotiated by Theresa May, but said nothing about Johnson's claim that the deal must be renegotiated.

Barnier said the EU would be willing to adapt a political text which goes alongside the withdrawal agreement.

EU leaders have long said that they won't reopen the 585-page legal text.

"We are ready also to rework the agreed Declaration on a new partnership," said Barnier.

In a brief speech Tuesday meant to rally the party faithful, Johnson sought to radiate optimism following his victory and promised to deliver Brexit.

Brexit hardliner Boris Johnson has won the race to lead Britain's governing Conservative Party, and will become the country's next prime minister.

He defeated his rival Jeremy Hunt overwhelmingly in a vote of Conservative Party members.

He will be installed as prime minister in a formal handover from Theresa May on Wednesday.

The victory is a triumph for the 55-year-old Johnson, an ambitious but erratic politician whose political career has veered between periods in high office and spells on the sidelines.

Johnson has vowed that Britain will quit the European Union, "come what may," on the scheduled Brexit departure date of Oct. 31 even if it means leaving without a divorce deal

But he faces a rocky ride from a Parliament determined to prevent him from taking the U.K. out of the bloc without a withdrawal agreement.

8:30 a.m.

Britain's governing Conservative Party is set to reveal who the name of the country's next prime minister, with Brexit champion Boris Johnson the strong favorite to get the job.

Party officials will announce Tuesday whether Johnson or rival Jeremy Hunt has won a ballot of about 160,000 Conservative members.

The winner replaces Theresa May, who announced her resignation last month, and will officially become prime minister on Wednesday.

It will be a huge upset if the winner is not Johnson, who has wooed Conservatives by promising to succeed where May failed and lead the U.K. out of the European Union on the scheduled date of Oct. 31 — with or without a divorce deal.

Several Conservative ministers have already announced they will resign to fight any push for a "no-deal" Brexit.
