On Thursday, the leaders of the three main parties in Britain take part in a crucial televised election debate on foreign policy.
The relatively unknown Liberal Democrat leader Nick Clegg was widely seen to have triumphed in last week’s live debate on domestic affairs, sending an electrical charge through the election campaign.
The Liberal Democrats' standing in opinion polls has soared - some polls have even put the Liberal Democrats in first place.
Although it is Gordon Brown's ruling Labour Party which Clegg's success has pushed into third position in the polls, it is David Cameron's Conservatives who stand to lose the most if the Lib Dem advance continues.
And so the world will be watching closely to see if Clegg can maintain his difference.
Topics for discussion include the war in Afghanistan, replacement of Britain’s Trident missile system, and Britain’s ties with Europe.
We want to hear from you – whether you watched the event on television or followed the debate via our online blog right here.
