The veteran Brexiteer will be one of seven party leaders or senior figures on a second panel when Boris Johnson and Jeremy Corbyn go head-to-head. Southampton is due to host the high profile debate on December 6, just six days before the general election.
However a huge row has broken out ahead of the event, with the Liberal Democrats arguing their leader has been unfairly excluded.
Mr Farage is also due to participate in a special election edition of Question Time ahead of the poll.
Last week the Brexit Party leader announced plans to field candidates in every seat in England, Wales and Scotland unless the local Conservative candidate vows to support a no deal Brexit.
Mr Farage has furiously attacked Mr Johnson’s Brexit withdrawal deal, arguing it is “not Brexit”.
However several of his own candidates have dropped out of the election and endorsed the Tories, saying they fear a split Brexiteer vote would led Labour take power.
The Brexit Party leader asserted: “It’s not Brexit – he is trying to sell a secondhand motor.
“He has polished up the bonnet but actually underneath nothing has changed.
“This is Mrs May’s appalling surrender treaty.
Instead they will all support one anti-Brexit candidate, drawn from one of their parties, in each constituency.
All three parties are determined to reverse the 2016 referendum result.
The pact was coordinated by ‘Unite to Remain’, an anti-Brexit group that promotes tactical voting.
However neither the Labour Party nor SNP, which are campaigning for a second EU membership referendum, are taking part.
The Liberal Democrats are furious their leader, Jo Swinson, won’t feature in the main debate and have threatened legal action.
Sky News has separately called for a debate on November 28 featuring the three main party leaders, but this has yet to be agreed.
On Twitter Ms Swinson angrily condemned the decision to exclude her from the main TV debate.
She commented: “A debate between Boris Johnson and Jeremy Corbyn shuts out the voice of Remain.
“An establishment stitch-up that shuts out the views of millions of people in the country.”
The Liberal Democrats have vowed to cancel Brexit without a second referendum if they win a majority in December.
