More than 10,000 companies have submitted their gender pay gap figures to the Government Equalities Office – but who are the worst offenders?

From healthcare providers to a budget airline, all the companies in the top 10 pay women more than two-thirds less than their male counterparts on average.

Here, the Press Association looks at the 10 companies with the highest median gender pay gaps, as of 1pm on Thursday.

NWN Media, which previously topped the list at 85.2%, no longer makes the top 10 after an incorrect entry in the Government database. The local newspaper company has a median gender pay gap of 85.2% in favour of women.

Ryanair has a pay gap much larger than its rivals – when comparing median hourly rates at the airline, for every £1 men earn, women earn just 28p.

It says the disparity is because of the number of UK pilots it employs – 546 are male and only eight are female.
