Bulgarian, British PMs Discuss Security, Economy

Borisov asked Cameron for information behind allegations that Iran and the Iranian-backed group Hezbollah were behind the July 18 terrorist attack in the Bulgaria city of Burgas, the government press service reported .

"We haven't received any such information to date. I asked David Cameron to provide it to me if he has it because, I repeat, these are very strong accusations," the Bulgarian premier said.

"I have asked [everybody] once again not to make any kinds of conclusions. As of today, we still have no information about the bomber... In this case, we have his head, face, perfectly preserved, we have a DNA profile and fingerprints. And nowhere in the databases around the world is there any information about this person," Borisov said.

Five Israeli tourists and one Bulgarian bus driver were killed on July 18 by an explosion at the Burgas Airport after a suicide bomber entered a bus bound for a seaside resort.

Borisov and Cameron's talks in London were dominated by discussion on cooperation in counter terrorism as well as prospects for deepening economic ties, according to official statements.

The two leaders discussed the possibility of British intelligence agents training their counterparts in Bulgaria's National Security Agency DANS.

Borisov and Cameron declared their mutual desire for stricter fiscal discipline in the EU.

"Mr. Borisov and I are working very closely within the EU for free markets, strict fiscal discipline, and trade with non-EU partners," Cameron told reporters after the meeting.

"We see eye to eye in many spheres and we are embracing joint policies in the EU, especially with respect to fiscal discipline and security," Borisov added, thanking Cameron for his backing of recent Bulgarian legislation authorizing the seizure of illegally acquired assets.

Borisov said the two also discussed "the future of key projects that are supposed to provide for the diversification of natural gas supplies to Europe."

"British Petroleum is willing to work on the Nabucco West project if it is economically efficient," the Bulgarian premier said after the meeting, referring to the downsized version of the EU-backed Nabucco gas transit pipeline, which aims to lessen European dependence on Russian gas.

While in London, Borisov also met with several Bulgarian athletes competing in the London Olympics.
