It seems that Facebook's algorithms are restricting who sees the petition when it is shared / posted to groups and - as a result - we do not have many signatures despite there being a pretty strong voice in favour of keeping our traditional post box and protecting our local post office. 

The Fareham Matters Facebook group has the most interaction, so I have continued to promote the petition there; however, I will be finalising this petition soon and sending it to the Royal Mail. 

Thank you all for your support!
