Education Minister John Della Bosca has quit the ministry pending the outcome of a police investigation into events that took place at a Gosford nightclub last weekend. 

Speaking in Bathurst after Premier Morris Iemma told a press conference the minister had been stood down, Mr Della Bosca insisted that he had done nothing wrong. 

Della Bosca's position had become untenable today, after a Herald report this morning that Mr Della Bosca had written the apology for the club to sign, even though his office had denied that he had done so.
