A survey showed more than three quarters disapproved of Mr Rajoy as head of the government, while 85 per cent had "little or no faith in him".
MADRID, Feb 25 (Reuters) - A former treasurer of Spain's ruling party, at the heart of a corruption scandal that has hurt Prime Minister Mariano Rajoy, was ordered to surrender his passport on Monday while judges investigate millions of euros he deposited in Swiss banks.
Luis Barcenas is accused of using his position to take bribes, evade taxes by hiding the proceeds in Switzerland and launder money through shell companies, charges that carry prison sentences of up to six years and fines
Ruz banned Barcenas from leaving Spain, seized his passport and ordered him to report to a court twice a month.
Public interest in the case had largely evaporated until January, when Ruz's investigation revealed Barcenas had Swiss bank accounts once worth as much as 22 million euros ($30 million).
Meanwhile, monthly jobs data out later is unlikely to calm nervous markets. Unemployment in Spain now stands at a staggering 26% with no signs of falling.
