When asked about his future while touring Penwith College, in Penzance in Cornwall, Mr Clegg said: "I will be MP for Sheffield Hallam and leader of the Liberal Democrats."
He also described the LibDems as the only party making pledges on building both a robust economy and a "fairer society" – something he said his party's coalition partners and the opposition lacked.
Asked if he intended to stand for re-election as an MP, Mr Clegg said: "Of course I am."
He added: "I can't predict the outcome of the next General Election. I think that the Liberal Democrats now are the only party offering two things: firstly, a commitment to building a stronger economy; and doing that in a fairer society, enabling everyone to get on in life.
"I think everybody now accepts you cannot rely on the Labour party to sort out the economy and we have a demonstrably greater commitment to fairness in society than the Conservatives.
"I think there are many people, in Cornwall and elsewhere, who want to see both of those things delivered."
