SOFIA, July 10 (Reuters) - Bulgaria's prime minister-designate Boiko Borisov called on the outgoing government on Friday to halt talks on major energy projects such as the South Stream gas pipeline until his new cabinet takes over.

Borisov said he was concerned the Socialist-led cabinet was making financial commitments that could worsen the budget situation in the European Union member state, hit by the global economic crisis and falling revenues.

"We are receiving worrying signals for acts in state-owned companies, which are not taking into account the financial and economic crisis and the interests of the country as a whole," he wrote in a letter to Economy and Energy Minister Petar Dimitrov.

The centre-right GERB party won by a landslide July 5 general election and its leader Borisov is expected to head a new government by the end of the month.
