David Mills, the husband of Culture Secretary Tessa Jowell, is expected to learn shortly whether he faces trial in Italy on a corruption charge.
The couple have now split up
Magistrates in Milan are deciding whether to indict Mr Mills and Italy's Prime Minister, Silvio Berlusconi.
It is alleged the lawyer was bribed by Mr Berlusconi to give false evidence in court. Both men deny the accusation.
Ms Jowell was cleared by Tony Blair of breaching the ministers' code of conduct over her husband's finances.
Questions were raised about her returns for the register for MPs' interests, which showed she had nothing to declare at the time when her husband received a £344,000 "gift".
But after interviewing the minister, the parliamentary commissioner for standards, Sir Philip Mawer, said there was no need to amend the entry.
Mr Mills and Ms Jowell announced the break-up of their marriage at the weekend, with Mr Mills' lawyer blaming this on the furore over the payment.
Both Mr Mills and Ms Jowell have denied any wrongdoing.
