Writer Jo Phillips and Nigel Nelson of the Sunday People joined the BBC News Channel to review the papers.
They discussed the Sunday Times story that David Cameron was considering inviting Ukip and the Green Party to join "the big three" for a pre-election televised leaders' debate next year.
They also looked at the Sun on Sunday's poll on voter perceptions of Ukip.
And they went north of the border to examine the front page of the Herald, the first Scottish national paper to back the Yes to independence camp.
