Peugeot 107 Horn Problems

The horn on my little runaround worked well for ages - indeed it was very easy to knock it and beep at innocent road users by mistake. It has now stopped working I have checked the fuse and that is fine. Any ideas?

i have a 2008 peugeot 107 sport 3 door and the horn has just stopped working.has anybody had this problem?is it the steering wheel pad or do i have to remove the bumper to get to the horn?is it a fuse?i am going to have a look this evening....

horn just keeps blowing, does not reset at all, the only way to stop it is a battery disconnect.
