Election 2015: Tories and Labour fight off coalition claims
The Conservatives and Labour have come under pressure over claims they could be forced into a post-election deal with UKIP or the SNP, respectively.
The polls suggest there may be a hung parliament after 7 May, raising the possibility of a coalition or a deal between different political parties.
Former Lib Dem leader Lord Ashdown said Thursday's inconclusive seven-way leaders' debate suggested another coalition was inevitable.
