Labour are held to a different standard because they are the party in opposition aspiring to be the party in charge. When your pitch to be elected is essentially boiling down to 'we are not the Tories' because the progressive, differential policies once proposed keep getting scrapped, they are going to get criticised as they are not offering an alternative to one of the worst governments of our time.
I have not visited this thread for a few months and in that time, Labour have reneged on the green pledge, the bankers bonuses cap, policies regarding trans rights and the nationalisation of water/rail. It is so uninspiring and makes it harder to convince people that politicians are not all the same when Labour are so scared of criticism from right wing voters and press. If you are being criticised by the Daily Mail for your policies, chances are you are doing something right.
