Legislation paving the way for the first major changes to charity law in 400 years is expected to be announced at the state opening of Parliament today.
Voluntary sector representatives feel that, although the Charities Bill may not be mentioned in the Queen's Speech, it will be included in papers setting out the Government's legislative programme.
"We are cautiously optimistic, verging on the confident," said NCVO's director of campaigns Chris Stalker.
Acevo chief executive Stephen Bubb said: "Her Majesty might not utter the words, but the bill should be in the briefing that comes with the speech. It would be strange indeed if it were not mentioned. It would blow a huge hole in relations between the voluntary sector and the Government."
