In June last year, a debate took place which included Penny Mordaunt making a claim about how much Labour would have to raise taxes. Angela Rayner disputed the figures, but there was a difference between the two. The party who was in government at the time knew the state of the economy, even though they hid it from Labour. The Conservatives claim ignorance now, but the debate shows that they knew the truth before the election.
The video above is an interesting take on how the Tories have ruined things over the 14 years in government, but as you can see from some of the photos that they have used, they have included a bit too much creative licence and have got a few things wrong as well.
In summary, I think that the Conservatives broke the economy and I also think that they hid what Labour would have to face once in power.
