No Government has the right to stop a citizen having a party (if it doesn't infringe on others) and every person should be able to see their community in a tradtional public house without breaking the bank.
Since time began people have been partying and ghave contributed to the well being a social development of mankind. The Labour Government saw fit to pass the criminal justice bill requiring social gatherings of more than a few people to need a license. If the land owner has no objections and there is consideration as to location (for volume reasons). There should be no problem.
Another thing is to cease the relentless attack on Britain's public houses- they are good for social cohesion. Better than people being stuck at home watching 'Britain's got talent ( an enormous amount of debt and out of control immigration!)'.
