Tony Blair has been questioned by police in the cash for honours probe.

Mr Blair was not interviewed under caution, suggesting he was questioned as a witness rather than a suspect and is unlikely to face criminal charges.

Several current and recent Cabinet members have already been interviewed by police, but this is the first time that the prime minister has been directly involved in the investigation.

Labour fundraiser Lord Levy had previously been arrested as part of the probe, which centres on claims that the some appointments may have breached a 1925 law making it illegal to hand out peerages in return for donations.

A number of large secret loans, totalling £14m, were made to the Labour party leading up to the general election in 2005 with some of the lenders nominated for honours.

Four businessmen who lent a combined £4.5m were offered peerages.

Critics say the terms of the loans meant they were in reality more donations than loans.
