Lord Hutton yesterday failed to end speculation over whether Defence Secretary Geoff Hoon will face another grilling at the inquiry into the death of David Kelly.

The law lord announced the witnesses called to give evidence on Monday but left pundits guessing whether key figures such as Mr Hoon, outgoing No10 director of communications Alastair Campbell, and BBC reporter Andrew Gilligan would be recalled.

The BBC's director general, Greg Dyke, will give evidence on Monday - the first day of the second phase of the inquiry - as will officials from the Defence Intelligence Staff (DIS).

But no other witnesses for the second phase of the inquiry were expected to be named until the hearing restarts.

Mr Hoon was widely expected to be recalled to face more questions about his involvement in the decision to name Dr Kelly as the probable source for Mr Gilligan's report, which claimed the Government "sexed up" its dossier on Iraq's weapons of mass destruction.

He has faced calls for his resignation after the parliamentary Intelligence and Security Committee (ISC) said his evidence to its inquiry into the Government's use of intelligence in the run-up to war in Iraq was "potentially misleading".

The committee said it was "disturbed" by Mr Hoon's failure to disclose full details of concerns among DIS about last September's dossier.

Lord Hutton may also want to question him about a meeting held in his office at the Ministry of Defence at which the circumstances in which Dr Kelly's name would be confirmed to journalists were discussed. Mr Hoon did not mention this meeting in his original evidence.

Mr Dyke was not a witness in the first phase of the inquiry and is likely to face questions about the BBC's dogged defence of Mr Gilligan's report, which claimed the Government "sexed up" its Iraqi weapons dossier.

He is also expected to be questioned on Mr Gilligan's e-mails to members of the Foreign Affairs Committee, which suggested questions which could be put to Government weapons expert Dr Kelly when he appeared before the select committee.

Lord Hutton heard 15 days of evidence from 63 witnesses before his week-long adjournment.

He has said he will sit for eight more days before retiring on September 25 to write his report.
