Turkey’s president approves new government led by ally

ANKARA, Turkey — Turkey’s president on Tuesday approved a new government formed by one of his most trusted allies, who immediately asserted the intention to institute constitutional reforms that would expand the powers of the presidency.

Many fear the system that Erdogan seeks will concentrate too many powers in the hands of the Turkish strongman, who has adopted an increasingly authoritarian style of governing, has cracked down on media and government critics and is accused of meddling in the running of the government in breach of the constitution.
