SIR - This month, more than half of the members of the European Parliament signed a written declaration drafted by Animal Defenders International calling for urgent action to end the use of apes and wild-caught monkeys in Europe's laboratories, and for a timetable to be established for the end of all primate experiments.

This represents an important political breakthrough and an opportunity for people to participate in a positive campaign to end the terrible suffering of these animals.

We urgently need the public's help to ensure the commitment expressed by the European Parliament becomes a reality.

A European Commission consultation found more than 80 per cent of respondents considered the use of primates in experiments as "not acceptable".

Increasingly, people are aware of the terrible suffering of primates in laboratories and also the problems of using the data obtained from primate experiments for products to be used by people.

More than 10,000 monkeys die in experiments in Europe every year. Now there is something you can do to help make it a thing of the past. Please visit for more information.
