Comedian Eddie Izzard, a renowned supporter of Labour, said: "The views on the NHS will resonate the most. We did rebuild it and David Cameron did say he would not touch it. He said he believed in it and suddenly they went all over it and we are going to have to rebuild it again.
"That got an instant standing ovation, which obviously wasn't planned as he had to stop in the middle of his speech, so that's great.
"I think fighting for women is great, the vote going down to 16 and 17-year-olds and fighting for people - the many not the few. I think that's the thing we always want to do."
Analysing the performance of the Labour leader, Izzard said: "I think it was very passionate. He's very confident now and very relaxed with his humour."
Ed Miliband has managed to find a style that suits him, and speaking well without notes always makes a good impression.
Miliband gave shape to the kind of government he plans to lead, arguing Labour is on the side of the working majority not the elite few.
Ed Miliband will promise to reverse business rates in a key speech tomorrow, which will be financed by not reducing corporation tax.
