This can be either direct or through those who already have some leverage like the media and indeed the general public. It can include demonstrations and even civil disobedience as forms of indirect lobbying.

Why Lobby
Although lobbying may not be the quickest way of getting
politicians to take the type of action you want, it is the accepted method in a
democracy. Since we do not advocate violence to coerce governments,
lobbying in its broadest sense is the most effective action we can take.
Some may argue that lobbying changes nothing and in fact the situation for the Palestinians has only gotten worse over the past 60 years. The evidence that lobbying does work is clear from the massive shift in politicians and media statements compared to any time in the past. This is very evident to those who have followed, for a longer period, the Israeli conflict in the Middle-East.

How to Lobby
Unless you have other routes to government ministers or
those who influence/advise them, your MP is your first and best port of
call. Since the EU is a significant player in this conflict, your MEPs are
also a key contact.
There are of course many different ways you can approach your MP/MEP. This very much depends on what it is you want to say and what you feel most comfortable with.
If you want to take action and start lobbying or you already lobby, but feel it is not as effective as youd want then talk to someone at the Exeter-PSCs lobbying sub-group.
