Shadow international development secretary Mary Creagh has thrown her hat into the ring to be the next Labour Party leader.

The Wakefield, West Yorkshire, MP joins an already crowded field to succeed Ed Miliband, and she told the BBC her party must "win back trust" on the economy.

Yvette Cooper, Andy Burnham, Chuka Umunna and Liz Kendall have already declared their intention to stand.

Meanwhile, shadow education secretary Tristram Hunt has told BBC's Question Time he is "interested" in the role. He said he would speak to party members on Friday.

Another potential candidate is Copeland MP Jamie Reed, who had a health brief under Ed Miliband. Talking to BBC Radio 5 live on Thursday 14 May, he repeated suggestions he was considering a bid.

Candidates must secure nominations from 34 colleagues - 15% of the party's MPs - by 15 June to make it on to ballot papers, which will be sent to members in August ahead of the leader's election a month later.

Creagh is the least high-profile of the candidates to declare so far but - as shadow environment secretary - took on the coalition government over the horsemeat crisis and attempts to sell off England's state-owned woodlands.

She told the BBC that her party Labour had failed to speak to people about "how they could win in the global race" and that her background of 10 years in business and "real experience of town hall Labour" could help win over voters.

"We have got to look at those areas which trust Labour to run their council services but where they chose not to put their trust in us to run the country," she said.

"We have to earn back the trust of large swathes of middle England who didn't trust us to run the economy for them and also to win back voters who chose the Scottish National Party... and large swathes of our industrial heartlands who chose UKIP."
