Contracts have gagging clauses

"The company hired to test flammable cladding on government-built buildings – in the wake of the Grenfell Tower fire – have been ‘gagged’ from criticizing Prime Minister Theresa May."

"Engineering firm WSP signed a UK government contract worth more than £100,000 (US$131,500) to carry out testing of cladding on buildings, 12 days after the Grenfell Tower fire in which 72 people died. A prerequisite of the deal was WSP having to sign a gagging clause preventing the company from being able to create `adverse publicity` for or `embarrass` PM May and her Cabinet Office, the Times reports... "

"Former Housing Minister Barwell was accused of `sitting on` ... a review into building regulations at tower blocks after a deadly fire in south London in 2009 killed six people."

"The revelations have been met with a mixture of disbelief and outrage on social media from across the political spectrum. Labour MP David Lammy, whose friend Khadija Saye died in the fire, said the gagging clause demonstrated `unforgivable cowardice`on the part of May. The Sun’s deputy political editor, Steve Hawkes, claimed it was an `awful look` for the UK government."
