For some MPs, Parliament is a lucrative business. For others, there are no perks at all. How did your MP boost his or her salary?

Richmond MP William Hague showed how to make Parliament work by earning up to £820,000 on top of his £57,485 Parliamentary salary. It was a huge increase on the previous year when he earned only an additional £350,000.

Darlington MP Alan Milburn gave up his £71,433 minister's salary to spend more time with his family, but recouped up to £85,000 from speeches, articles and advice.

It is impossible to calculate the precise amounts earned by MPs outside Parliament, because they are not required to register the sums received from directorships, shares or properties.

Fees for speeches, television appearances, Press articles and other jobs are recorded only in bands of £5,000, so a payment of only a few hundred pounds appears in the register as "Up to £5,000".

The vast majority of North-East MPs, however, take nothing or only have their expenses paid for a working trip overseas. These are the declared interests of MPs in County Durham, Teesside and North Yorkshire:
