Nicholas Leonard: Brown is on a collision course with chancellor over economy
British Prime Minister Gordon Brown and Conservative leader David Cameron have at least two things in common. They both like munching Kit Kat chocolate bars when they are under stress and they are both determined to keep Britain out of the eurozone.
Brown spent 10 years as chancellor resisting pressure from Tony Blair to get rid of the pound in favour of the euro and Cameron last week pledged that he would "never" make such a move.
Eurosceptic MPs believe the crisis triggered by Greece in the eurozone is proof of their long-standing view that superimposing monetary union on separately governed economies cannot work.
