A spokesperson said: "We know that a lot of criminal activities happen at parties so having a member of the Government present allows us to witness this behaviour first hand whilst holding a mini sausage roll in the other hand. That way we can go back and produce more relevant legislation and reduce our expenses claims for mini sausage rolls".
Liberal Democrats within the coalition say they will block the move. One senior Lib Dem source said: "This is typical Theresa. She suffers with serious FOMO everytime there's a party going on. Last year she crashed our party conference because she heard we had opened a bottle of Waitrose Prosecco in the hotel. I wouldn't mind but I'd opened it in the privacy of my own hotel room. Imagine my surprise when I discovered Theresa May sipping from a champagne flute whilst using my bidet".
This move follows on from several other controversial bills including one where the Transport Minister announced that he was going to turn up on people's driveways to kick their tyres.
