The Owen Patterson scandal has put MPs' second jobs and lobbying rules firmly in the spotlight.
The Standards Committee found Mr Paterson “repeatedly” broke parliamentary rules by lobbing for health tech firm Randox and meat producer Lynn's Country Foods - companies which paid him more than £100,000 a year as a consultant.
Many MPs take on a variety of extra work to supplement their £81,932 salary. It is not against the rules to have a second job or provide consultancy work to businesses.
However, they must record it in the register of financial interests and must not lobby Government on behalf of the companies that pay them.
Several London MPs have earnt more than £10,000 on top of their parliamentary salary in the last two years.
On Monday, international trade secretary Anne-Marie Trevelyan said she would not back a ban on MPs having second jobs.
But she said she would consider a plan for MPs to be barred from paid lobbying on behalf of commercial interests, as Paterson did.
“I think the question of MPs having jobs that involve lobbying perhaps should be looked at again,” she said. “But, across the board, I don’t think we should have a removal of the ability to maintain a second job, because it brings a richness to our role as members of parliament.”
Here are the London MPs who declared the most from second jobs. There is no suggestion of wrongdoing.
