Downing Street asserted last week that it needs time to review the politically sensitive 50-page dossier, citing the security implications of making public the report by Parliament’s Intelligence and Security Committee.

But the chairman of that panel, Dominic Grieve, called the suppression of the document “jaw-dropping,” while critics have accused Johnson of withholding allegations in the report that could be damaging to his Conservative Party ahead of voting next month.

“I’m dumbfounded that this government won’t release the report about Russian influence because every person who votes in this country deserves to see that report before your election happens,” Clinton told the BBC Radio 4's "Today" news program in remarks that aired Tuesday.

“That should be [an] absolute condition because there is no doubt — we know it in our country, we have seen it in Europe, we’ve seen it here — that Russia, in particular, is determined to try to shape the politics of Western democracies not to our benefit, but to theirs,” she continued.

Clinton’s White House campaign against Donald Trump three years ago was marred by Kremlin meddling. She has partially blamed Russian interference for her loss, and former special counsel Robert Mueller concluded in his report that Russia’s government “interfered in the 2016 presidential election in sweeping and systematic fashion.”
