Is Sarkozy headed for the Élysée Palace exit? Will Ken again lord it over London (over 30 years after he was first elected leader of the Greater London Council)? Is the far right Gold Dawn party set to win its first seats in Greece’s first elections since the country’s bail-out? Will the Lib Dems or the Tories bear the brunt of voters’ discontent with the coalition in national local elections? At the start of a week to be dominated by polls and ballot boxes, these are interesting times.
