Behind the scenes at the construction of Hinkley Point C. Plus, The Great British Sewing Bee reaches the quarter-finals. Here's what to watch this evening

With an estimated construction cost of between 21.5bn and 22.5bn, the nuclear power plant in question - Hinkley Point C - was one of eight announced by the government in 2010, but the only one on which work has since commenced, meaning it will become the first nuclear power station to have been built in the UK in more than 20 years. This series goes behind the scenes of the project, as workers struggle to keep to their deadlines while digging the reactor's foundations. Ammar Kalia
