There is currently an open petition to introduce a law that recognises Parental Alienation as a criminal offence, that seems to be gaining some momentum. 6500 signatures and the government has to respond at 10000 signatures. This form of abuse affects Mums, Dads, Step parents, Grandparents and wider family.
Rather depressingly, twice as many people have signed a petition asking for a law to protect brown hares!?!
Hopefully this link will work, but I am a computer biff so if it doesn't please could someone who knows what they are doing post it?
