Announcing Labour's plans, leader Jeremy Corbyn said: "The British people are united in their resolve that terror will not prevail. It will not prevent us going about our daily lives or derail our democratic process.
"Resuming democratic debate and campaigning is an essential mark of the country's determination to defend our democracy and the unity that the terrorists have sought to attack."
All the major parties suspended national campaigning after Monday's bombing at the Manchester Arena.
Local Labour activists did some low-key campaigning on Wednesday, such as delivering leaflets, but nothing which involved contact with voters.
Mr Nuttall, who is a UKIP Member of the European Parliament for the North West of England said everyone was "horrified by the horrific events that took place in Manchester" and it had been "right and proper" for political parties to suspend their election campaigns "for a short period as a mark of respect to those who lost their lives or suffered appalling injuries".
"But we cannot be cowed or allow our way of life to be undermined by those who wish to do us harm," he said.
"These people hate the way we live, hate our freedom and hate our democracy.
"The best response we can make is to ensure that the democratic process continues and therefore I have decided that we must to go ahead with the launch of the UKIP general election manifesto tomorrow.
"For those who say that nothing must change, but then complain, it is by prolonging the disruption to normality that we allow the terrorists to win. Politics has never been more important, politicians must deal with these issues."
