Yvette Cooper insists voters in the EU referendum won't listen to advice given by Nigel Farage or Boris Johnson.
The vote will take place across the country on June 23, and Cooper is firmly part of the Remain campaign, led by David Cameron.
The Labour MP for Pontefract and Castleford believes Farage isn't a strong campaigner, with no evidence to back up the claims he makes, and she feels voters won't be influenced by his comments about the Leave campaign.
"The idea Nigel Farage is somehow a champion for the little guy across Britain is a load of rubbish," she told Paul Ross. "I don't think people are going to judge it on the bizarre things Boris Johnson or Nigel Farage say.
"Nigel Farage has never stood up for the lowest paid people in the country. He's someone who's said he'd rather have private healthcare than the National Health Service."
Cooper doesn't believe those opposed to remaining within the EU have enough knowledge of the changes which would take please if the UK were to leave.
"The Leave campaign can't tell us what it would mean if we went out, they can't tell us what the trade deal would be," she added. "We know it would be worse, the cost of trade would be higher.
"What we get back in terms of trade is so much bigger [within the EU]. I just don't want to vote to put people's jobs at risk.
"All the trade unions across Britain are saying we need to stay in, because it helps underpin our workers' rights."
