MEXICO CITY (Reuters) - Mexican President Enrique Pena Nieto faced fresh questions on Wednesday about his dealings with a company at the centre of a conflict-of-interest scandal, after it emerged that he enjoyed rent-free use of a house belonging to the firm as a campaign office.

Already under pressure over the government's handling of the presumed massacre of 43 students abducted by corrupt police in southwestern Mexico in September, Pena Nieto is facing his most difficult period since taking office two years ago.
