International Perspective - Lessons from Berlin?

On 1 June 2015, Berlin began enforcing rent controls preventing landlords from charging  over  10% more  than  the  local  average  rent  for  new tenants.   The chairman of  the Berlin  Tenants Association has  apparently  reported that  “we don’t want a situation like in London”.  It seems that London’s housing system has now become so completely dysfunctional that its reputation has spread far and wide.  Is it time for the UK’s hard-pressed tenants to clamour for the same rights as their Berlin counterparts?
