The Prime Minister is set to make further announcements about embattled National MP Todd Barclay.

Mr Barclay's political future is in doubt after he misled Bill English and the public over secret recordings he's alleged to have made of a former electorate staffer.

Mr English is hinting of a pending development.

"There's ongoing discussions, but I'll have more to say at two o'clock," he said.

Ditching Todd Barclay against his wishes could prove difficult for National.

According to the party's rules Mr Barclay's own electorate executive would have to seek approval from National's board for his nomination endorsement to be revoked.

If approved, Mr Barclay would have to be given the chance to state his case at a Party board meeting - a majority decision could see his nomination reversed.

However, such process a could be legally challenged and with candidate nominations having to be finalised by the 23rd of August, the timeframe is tight for the issue to be resolved.
