Image source, PADeputy Labour leader Harriet Harman is the latest from her party to be asked about a possible deal with the SNP after the election. She told Sky News' Murnaghan: "It's not a sensible question... The question is put forward by two sides.

She adds: "We are planning and working towards a majority."

Prof Rosemary Hollis, from City University, says part of the charisma of IS, what makes it appealing to a minority, is the idea nothing is too brutal. She says those fighting against the group are not universally popular either - there are monarchies and regimes lined up in a battle for power for power's sake.
