German election campaign heats up as Merkel's conservatives slide
BERLIN, Aug 29 (Reuters) - The campaign over who will replace German Chancellor Angela Merkel heated up on Sunday after an opinion poll showed the centre-left Social Democrats (SPD) opening up a bigger lead over Merkel's conservatives.
Support for the SPD rose two points from last week to 24%, their highest result in four years according to the INSA poll conducted for the Bild am Sonntag newspaper. The conservatives slipped one point to 21%, their lowest ever polled by INSA.
