Livingston have secured the services of former Dundee United and St Johnstone midfielder David Robertson, who ended last season with Morton.
The 27-year-old started his career at Tannadice before moving to Saints in 2011 but his time there was marred by a broken leg.
He moved to Morton in January of this year and played 16 times as they fought unsuccessfully against relegation.
Robertson said: “I am delighted to get fixed up again at a Championship club. It is going to be a challenging season but one I am looking forward to.”
