MPs who state beliefs as fact with no supporting evidence must be disciplined.

There is a modern trend in politics for MPs and their representatives to spout fabricated information as if it were fact, which can have a resonant (but groundless) effect on the audience. In order to maintain credibility the government must actively oppose the "post-truth" era.

We're not sure what action you would like the UK Government or Parliament to take.
If you would like it to be illegal for politicians to lie or mislead the public, you might like to sign this petition:

Make it illegal for any UK political figure to knowingly lie or mislead.

Otherwise, you could start a new petition explaining clearly what you would like the Government or Parliament to do.
