The Home Office is increasingly making use of an arbitrary "good character" clause to deny applications of British citizenship. Falling foul of this clause includes any record of minor offenses (including speeding tickets), looking to too eccentric, or - bizarrely - being too promiscuous.
This means that someone who wants to naturalise and passes all other standards - i.e. has the means to support themselves financially, has lived here for a sufficiently long period, has passed the English language and Life in the UK tests, paid their NHS surcharges, etc., can be denied UK citizenship because of their sex lives or how they dress. About 40% of citizenship applications are denied under this clause.
This is disgraceful. We are always hearing that "good immigrants" with something to offer are welcome, but are willing to deny naturalisation based on utterly flimsy criteria in order to meet an arbitrary 100k target. The target obsessed culture in the HO is making us look like a paranoid backwater that just hates all foreigners.
