The Christian Democrats have become the latest party to unveil their draft manifesto for the general election next March, and focus on a regional approach alongside a crackdown on drugs.

Top of the list of party concerns is the need to strengthen the role of MPs in their own region or city, the draft manifesto states. Rather than elect all 150 MPs on the basis of party lists, the CDA says100 should be elected by 12 to 15 more local constituencies.

The advantage of this, says Pieter Omtzigt, who helped draw up the manifesto, is that MPs will focus more on their own regions and representing their own voters. Seats in parliament are currently divided up according to how many votes each party wins on a national basis.

The CDA also wants to invest €10bn in a programme of house building and improving public transport, including the development of more national high speed train routes.

The party would also like to allocate €400m to tackling drugs crime, which will include measures to reduce recreational drugs use.

The CDA, the second biggest party in the current coalition with 19 seats in the 150-seat parliament, will go into the election campaign with a new leader – health minister Hugo de Jonge. According to the most recent poll of polls, the party is on target to win 12 to 16 seats in the March vote.

The Liberal democratic party D66 and the SP have already presented their draft manifestos, while the VVD has hinted that support for nuclear power will be a major part of theirs.
