At its recent conference, the youth wing of the UK Liberal Democrats has passed a resolution which criticizes the Libdem members of the European Parliament (MEPs) for voting in favour of software patents. The UK Libdems in the European Parliament, led by Diana Wallis and Andrew Duff, had voted against the party's previous policy papers and against their own public statements. Instead they had followed the recommendations of Arlene McCarthy and the UK Patent Office. The Libdem Youth explains why it is important that this course be corrected before the second reading in the European Parliament. The resolution specifically demands that the party should sign the petition initiated by FFII. FFII UK has a documentation about the Liberal Democrats and about the UK MEPs in general. The voting behaviour of the Libdem MEPs can also be studied in our analysis of the vote.
