It remains unclear whether any Conservative party officials remain at the centre of a police inquiry in relation to electoral expenses.

Simon Day, the Conservative Party’s treasurer, was reported to the police by the Electoral Commission in March after the watchdog’s inquiries found that the party’s general election return was “neither complete or correct”.

In March, the Met was still investigating an allegation in relation to expenses irregularities while two others remained under assessment.

The Guardian has asked the Conservatives to confirm whether Day has been told if he is at present under investigation.
