Following decades of debate, UK Treasury chief Rachel Reeves has backed the construction of a third runway at Heathrow Airport, asserting it could create over 100,000 jobs and enhance the UK’s connectivity and economy. The government plans to invite proposals this summer while addressing environmental concerns raised by critics including London Mayor Sadiq Khan. Although parliamentary approval was granted in 2018, the project faced delays due to legal challenges and the pandemic. The government aims for planning permission by 2029, amidst calls to balance growth with climate objectives.
