Ed Miliband has led David Cameron in approval ratings on Twitter this week.

The Labour leader beat the Prime Minister in the number of net positive references on Twitter every day, according to the latest data.

But Mr Cameron won the greatest number of mentions on Twitter of all the seven main party leaders - a total of 26,850.

With just under two weeks to go until the General Election, both main party leaders have seen a jump in their profiles on social media. This has not always been for positive reasons, however.

Mr Cameron received the most mentions on April 22, but enough of them were negative to ensure he came in the bottom five of the Press Association's daily chart of top 40 political movers and shakers on Twitter.

And neither he nor Mr Miliband topped the chart on any day throughout the week.

Instead it was figures from some of the smaller parties that won the highest net number of positive mentions on Twitter, with Plaid Cymru leader Leanne Wood topping the chart on three of the past seven days.

But Mr Miliband managed to end the week comfortably ahead of Mr Cameron in terms of approval ratings, with the Labour leader's score improving over the course of the week from 44% to 59%.

Health Secretary Jeremy Hunt scored the lowest net approval rating of the week, when he polled a score of minus 14% on April 18. He had received a mixed response after retweeting a graph showing that more GPs were planning to vote Conservative than Labour.

Other politicians scoring low approval ratings this week were Liberal Democrat leader Nick Clegg (10%) and Ukip politicians Patrick O'Flynn (26%) and Mark Reckless (29%).
