Voters are heading to the polls, watching and waiting. In the UK, a six-week campaign has reached its conclusion and voting is underway in the country’s general election, amid widespread expectation that the Labour party will return to power for the first time since 2010. For extensive coverage of the campaign, commissioned by the superb politics team in London, click here. There’ll be regular updates as results come in after 10pm UK time (11pm CET).

Across the Channel meanwhile, France is between the two rounds of its snap legislative elections, with the far right emerging as the leading group after last weekend’s voting. Our Paris bureau has provided a range of excellent coverage from leading French researchers throughout this key period in the country’s history.

Both editions will provide fresh analysis and explanations as the makeup of the next governments of France and the UK become apparent in the days ahead. We’ll also publish a podcast next week that brings political researchers from both countries together to discuss the emerging picture.

Until then, as ever, there’s a broad range of content on The Conversation from across the academy, touching, for example, on tennis, psychedelic science, genomic research and … the height of Dutch people.
