Strict new rules on MPs employing their spouses and relatives will be revealed by the Commons expenses watchdog this week.
The reform, expected to take effect this month, comes amid concerns that Westminster could face a scandal such as that which has engulfed the French presidential candidate François Fillon, whose wife and children are alleged to have received €1 million as his parliamentary assistants.
The rules will urge British MPs to ensure that all jobs in their parliamentary offices are advertised and that candidates with no links to them are among those interviewed. MPs will have to issue justifications for hiring relatives, in an effort to boost public confidence in the recruitment process. The reform will fall short of the blanket ban on employing family members imposed in the Scottish parliament.
