BBC News says Hungary has agreed to change a law criticised for undermining the independence of the country's central bank.

The concession, announced by the commission, means negotiations over a €15 to 20bn bailout package can now reopen.

The Hungarian government faces serious problems in its banks, as well as a rising cost of borrowing.

But prime minister Viktor Orbán has been criticised for undermining democratic protections in his country, says the broadcaster.
