The Institute for Fiscal Studies (IFS) has criticized both the Conservative and Labour parties for their lack of transparency on tax policies. The think tank has accused both parties of making unrealistic claims and promises regarding taxes, as well as making pledges for the National Health Service (NHS) that are essentially unfunded. The IFS has called out what they describe as a "conspiracy of silence" from both parties when it comes to addressing the issue of taxes and funding for public services.

In a heated exchange during a seven-party BBC election debate, Penny Mordaunt and Angela Rayner clashed repeatedly on the topics of tax and defense. The debate became fiery as the two politicians debated their opposing views on these crucial issues.
