Sieve Agency?

The leader of Reform UK and his deputy are suing the Notional Crime Agency, the UK’s alleged FBI equivalent, over leaks of their financial affairs. The Reformers are after damages and the names of those to whom NCA minjions passed information.
    There is an NCA internal investigation ongoing into the leaks but the Reformers feel that it has progressed to stalling and is now heading for cover-up country.
