Solomon Islands Prime Minister Matthew Wale Departs PIF Meeting Amid Leadership Challenge

Solomon Islands prime minister and outgoing Pacific Islands Forum (PIF) chair Matthew Wale has made a shock departure from the PIF leaders meeting, flying out of Palau just hours after arriving, in order to deal with a looming leadership challenge back home.

Mr Wale's political coalition was shaken yesterday after Solomon Islands Home Affairs Minister Manasseh Maelanga announced he had filed a no-confidence motion to topple Mr Wale, who has only been in the top job for three months.

In his motion, Mr Maelanga accused Mr Wale of "repeatedly making decisions of matters of national importance without proper consultation with, or the approval of, cabinet, thereby undermining the principles of collective cabinet responsibility, representative democracy and good governance".

Mr Maelanga was one of Mr Wale's main challengers for the top job this year, and has held a senior position in his cabinet since then.

But his arguments echo many of those made by the Solomon Islands opposition, whose leader, former prime minister Manasseh Sogavare, has accused Mr Wale of bulldozing through major changes without consulting properly with parliament or the electorate.

Mr Wale appeared to be shaken by the news on arrival in Palau on Saturday night, and declined to comment on the challenge when asked about it by reporters.

The ABC understands Mr Wale left Palau early on Sunday morning and is due to arrive back in Solomon Islands on Monday.

Two of Mr Wale's key lieutenants in his coalition — Foreign Minister Rick Hou and Peter Kenilorea Jr — will now represent Solomon Islands at the meeting.

Mr Kenilorea Jr said in Palau late yesterday that he "had no idea as to why" the challenge was launched.

"[I'm] looking forward to finding out more," he said.

The news is a blow to the PIF, which is already facing a large number of absent leaders at this year's gathering.

Kiribati's President Taneti Maamau announced yesterday he would not attend, and that his nation would be represented instead by its ambassador to China.

Samoa's Prime Minister Laʻauli Leuatea Schmidt and Vanuatu's Prime Minister Jotham Napat are also not set to attend, while it's unclear whether Fiji's Prime Minister Sitiveni Rabuka will fly to Palau for the meeting.

The challenge will also unsettle Australia, which sees Mr Wale as far more sympathetic than his predecessors Jeremiah Manale and Manasseh Sogavare.

Mr Wale fiercely criticised China's recent ballistic missile launch and has made it clear he is uneasy with China's security role in Solomon Islands — although he has not tried to tear up the 2022 agreement the Pacific nation signed with Beijing.

He also announced not long after taking power that he had agreed to kick off negotiations with Australia on a new treaty — with officials racing to complete the discussions by the end of this year.
