A secret Russian-funded network is attempting to disrupt upcoming democratic elections in an eastern European state, the BBC has found. Using an undercover reporter, we discovered the network promised to pay participants if they posted pro-Russian propaganda and fake news undermining Moldova's pro-EU ruling party ahead of the country's 28 September parliamentary ballot. Participants were paid to find supporters of Moldova's pro-Russia opposition to secretly record - and also to carry out a so-called poll. This was done in the name of a non-existent organisation, making it illegal. The results of this selective sampling, an organiser from the network suggested, could lay the groundwork to question the outcome of the election.

While some of the fake clips and comments shared by this group of accounts on X were clearly absurd and satirical, others falsely portrayed candidates saying politically damaging things. In the comments, the network of X users works to make them appear believable. The videos have racked up tens of thousands of views. One post included a doctored video of Wes Streeting, the shadow health secretary, on the BBC's Politics Live show. As the presenter discusses politician Diane Abbott, the footage is made to sound as though Mr Streeting is saying "silly woman" under his breath - but he never said those words.

Google is hosting adverts for unofficial services like applying for a visa that charge vastly inflated amounts, a BBC investigation has revealed. The search engine returned ads for services charging £50 to change an address on a driving licence – something that can be done for free on the government's website. Applying for an ESTA travel permit on the US government's website should cost no more than £10 ($14). But Google'repeatedly' allowed ads for websites charging more than £58 ($80) for an ESTA, the BBC found. Adverts for unofficial services selling government documents are against Google's own rules.

A Parliamentary committee looking at cheating claims in Paralympic sports is set to hear "explosive" evidence on Tuesday, according to one witness. MPs will discuss the classification process after a BBC investigation uncovered claims of tactics being used to cheat the system internationally. Michael Breen, father of Paralympian Olivia, will be among the witnesses. "I firmly believe that the evidence will be extremely powerful, one might even use the word explosive," he said. The BBC investigation claimed tactics such as taping up of arms, taking cold showers in trunks and even surgery to shorten limbs had been used to get into a more favourable class.
