Len McCluskey, the general secretary of Unite has categorically denied that unions are considering disaffiliating from Labour.
"This idea that we are considering disaffiliating from the Labour Party is nonsense," he told ITV News political correspondent Emily Morgan today.
He added: "In many ways the Labour Party has never been as united as it currently is."
Jim Murphy launched a broadside attack on Unite boss Len McCluskey as he announced he will resign as leader of the Scottish Labour party.
Mr Murphy said that while trade unionists were "a source of enormous strength and moral purpose" to Labour, the party should not be beholden "to one man."
One of the things about stepping down is that you can say things in public that so many people in the Labour party only say in private. So whether it's in Scotland and the contest to come across the UK. We cannot have our leaders selected - or de-selected - by the grudges and grievances of one prominent man.
The leader of the Scottish Labour party doesn't serve at the grace of Len McCluskey. And the next leader of the UK Labour party should not be picked by Len McCluskey.
A union has welcomed Conservative plans to give emplyess three days paid leave to take part in voluntary wor.
The TUC said that members would be able to use the time to get more involved in their union.
The TUC has long called for a Community Day Bank Holiday to encourage volunteering and community engagement. We therefore welcome any move that makes employers recognise the benefits of volunteering and social action.
Trade unions are the UK's biggest voluntary groups. This new right will give every union member a guaranteed three days for time off to get involved with union activities.
A union boss has attacked the Prime Minister for suggesting private sector pay rises when most of the country has seen a real terms pay cut - particularly in the public sector.
Paul Nowak, assistant general secretary of the TUC, said: "If David Cameron wants business leaders to take his message ... seriously, he needs to take practical pay to boost the pay of our doctors, our nurses, our local government workers."
Unison said a new offer on NHS pay means that more than 250,000 of the lowest paid workers will get a pay rise of between 2.2% and 5.6% next year.
Health Secretary Jeremy Hunt has said that an NHS payrise, offered as a way of averting strike action by health workers, would not cost the taxpayer any more money:
The deal we've put forward on NHS pay is good news for patients, and I welcome the unions calling off strike action.
We've consistently said we wouldn't agree to anything that risked jobs and patient safety - and the NHS paybill won't increase next year.
But this pay offer gives 1.1m hardworking NHS staff a payrise without costing the taxpayer more money. The lowest paid will get £800 more.
Union leaders have cautiously welcomed a new offer from the Government in an ongoing row over pay.
Unison's head of health Christina McAnea said it "isn't a great offer" but that it would consult its members on the new terms.
The GMB amd Unite unions both said they too would consult members on the new offer.
Dr Peter Carter, general secretary of the Royal College of Nursing, said the "breakthrough" was a "positive start, but there is more to be done".
Planned strikes by health workers in England and Northern Ireland have been suspended, unions announced today.
It follows new offers made to union leaders in talks with the Department of Health, which are believed to include:
- A consolidated 1% payment for staff up to senior level
- An additional £200 consolidated payment for lower paid staff
- Abolition of the first point on the pay scale, and the second raised to £15,100.
The industrial action had been planned for Thursday and next month in a row over pay.
Talks aimed at averting next week's NHS strike have adjourned and will resume on Monday, unions have said.
The GMB union has issued formal notice of a strike by health workers planned for 29th January.
It comes as union officials return to talks with the Government later today aimed at averting industrial action.
GMB said it had served NHS employers in England and Northern Ireland with the necessary information about the stoppage involving hospital and ambulance workers.
Ambulance members of the union will strike for 24 hours from 0001, while other health workers will take action for 12 hours from midday.
Members of Unison and Unite are also set to go on strike on the same day.
