In April 2011, Shadow Chancellor Ed Balls became an internet sensation after he tweeted his own name.

Balls social media fail became so popular that Twitter celebrates #edballsday every year on 28 April. So clearly, it’s a joke that never gets old.

The Deputy Prime Minister yesterday simply tweeted “Ed Balls”.

Moments after Clegg’s tweet, Balls replied:  “I agree with Nick”.

The tweet comes after Balls hinted at a coalition between Lib Dems and Labour in an interview with a New Statesman.

Balls told the New Statesman: “I can disagree with Nick Clegg on some of the things he did but I’ve no reason to doubt his integrity, we’ve never, I don’t think, ever had a cross word.

“We’re fighting hard for a majority, who knows how things will turn out, I think, look, very many Labour Party members, voters, supporters, would find that very difficult and some Liberal Democrat voters would find that very difficult as well, but we’ll deal with the situation as we find it.”
