there is two ways to delete them..
1. in class a you can :
self.write(cr, uid, ids[0], {'connect': [(2, c.id) for c in list  ]
#write list of tuples (2, c.id ) for every c in list wich calls orm unlink method on those records

or simply:

2.
cr.execute("delete from b where connect = a.id")    #where a.id is id of recors in model a for wich you want items deleted....

Hope it helps..
