These are the top 10 MPs who have earned, or will earn, the most from outside work in 2021.

MPs are paid a salary of £81,932 a year, but second jobs have been in the spotlight since the resignation of former North Shropshire MP Owen Paterson in a lobbying scandal.

Fresh scrutiny has been applied after it was revealed former Attorney General Sir Geoffrey Cox was being paid hundreds of thousands of pounds advising the British Virgin Islands’ government in a corruption investigation.

The PA news agency has analysed the figures provided in the most recent publication of the register of financial interests for MPs.

The analysis only includes payments that have been received – or are expected to be received – in 2021, although in some cases work was carried out in 2020.

In cases where positions have started or ended part way through the year, the figure has been calculated pro-rata.
