What time will we get General Election results? Your hour-by-hour guide and estimated declaration time for each constituency

In just a few hours we will start to see the results of the most seismic general election in a quarter of a century. Midnight Swindon South is likely to be the first battleground seat of the night to declare at around 12.15am, where former justice secretary Sir Robert Buckland is defending a majority of 5,650 and where Labour candidate Heidi Alexander - who was MP for Lewisham East from 2010-18 - needs a swing of 5.7 percentage points to win. Former House of Commons leader Sir Jacob Rees-Mogg will learn if he has won the new seat of Somerset North East & Hanham, where the notional Tory majority is 16,389 and which Labour would take on a swing of 14.3 percentage points, ranking it at number 165 on the party's target list. The Leicestershire constituency of Loughborough, a bellwether at every general election since February 1974, is due to declare at around 5.30am; Labour needs a 5.9-point swing to gain the seat from the Tories. 6am Among the final results to declare should be the London boroughs of Ilford North and Ilford South, both safe for Labour; the new constituency of Selby in North Yorkshire, which Keir Mather - the youngest MP at the end of the last parliament - is hoping to win for Labour and overturn a notional Tory majority of 14,838; and Farnham & Bordon, a new seat that straddles the borders of Hampshire and Surrey, which could bring the Lib Dems a late gain at the expense of the Conservatives.
