Exclusive: PM pleads with former Liberal members to rejoin party

Prime Minister Scott Morrison has sent letters to former members of the Liberal Party, pleading for them to rejoin ahead of the federal election.

"I know some people have left our Party for various reasons over the years," the letter reads.

"I wanted to write personally and encourage you to rejoin the Liberal Party."

With the New South Wales election in March and the federal election due in May, it appears Scott Morrison is trying to rally support at a grassroots level.

"We need everyone who believes in our values to become energised members of our movement," he writes.

"Very importantly, there is a Shorten-led Labor Party to defeat at the next election. To achieve this, we need you back."

The letter was signed by Mr Morrison, who was today on the campaign trail in Brisbane, and authorised by NSW Liberal Party State Director Chris Stone.

While a copy of the letter obtained by Nine News is not dated, it comes just one week after former federal Labor Party President Warren Mundine was parachuted into the federal seat of Gilmore as the Liberal candidate.

It was a captain's pick by the Prime Minister, which sparked the resignation of the dumped locally-endorsed Liberal candidate Grant Schultz, along with a number of disillusioned Liberal Party branch members.

The Prime Minister’s office would not comment on the email but a senior Liberal source said that since September membership in the NSW Division had risen by 9,7 per cent.
