A big row is taking place about politicians and the money they are given to do their jobs.

As well as a wage they are also allowed to claim extra cash - called expenses - for things they can't do their jobs without.

Now a lot of them have been forced to give some of the money back, because they've been spending expenses on things they shouldn't have.

When the story first started we asked BBC political editor Nick Robinson to explain why politicians are allowed to claim expenses.
