French police on Thursday began questioning one of President Nicolas Sarkozy's key ministers as a witness in an investigation into a political donations scandal that has rocked the government.
The questioning of Eric Woerth, social affairs minister, took place at the finance ministry where Mr Woerth has been tasked by President Sarkozy with steering his controversial pension reform programme.
Mr Woerth, who was previously budget minister, resigned as treasurer of the ruling centre-right UMP this month amid suggestions of a potential conflict of interest.
