The latest Ipsos Synovate opinion poll is the second to emphasise the sharp rise in popularity of the Socialist Party this week.

The poll says the SP would take 29 seats in parliament if there was a general election tomorrow, up seven on two weeks ago.
At the same time, support for the anti-Islam PVV is down four seats, from 24 to 20, the Synovate poll shows.
On Sunday, a Maurice de Hond poll made the SP the biggest party, overtaking the ruling VVD. Synovate puts the VVD ahead on 32 seats.
SP leader Emile Roemer is the most popular leader in the Synovate poll, with a 7.1 approval rating. Geert Wilders is least popular with a score of 4.2.
