German elections are usually dull affairs - but it's different this time

Germans will be voting in a general election next weekend.

The country has the largest population - 84 million - and the biggest economy in Europe with a GDP of $4.5trn, but its elections are usually dull affairs.

Since the Second World War, there has been agreement between the two ruling centre-right and centre-left political groupings, who have even ended up sometimes forming a grand coalition.
