St Mirren defender Kirk Broadfoot will join Rangers in the summer after the 22-year-old signed a pre-contract agreement with the Ibrox club.
Broadfoot will be a Rangers player next season
Rangers manager Walter Smith told his club website: "He has played very well for St Mirren in the SPL this season.
"He has gained vital experience and will be a welcome addition to our squad next season."
He becomes Smith's second pre-contract signing for next season, joining Falkirk striker Alan Gow.
Broadfoot arrived at St Mirren Park from Hibernian in 2002 and has gone on to represent Scotland at under-21 and B levels.
Agent Graeme Rankin told BBC Sport: "Kirk can only thank Gus MacPherson and the St Mirren coaching staff for bringing him on and giving him the chance to go to Rangers.
"He is delighted to get the chance to go to the club he supported as a boy."
Rankin pointed out that St Mirren would be due compensation even if he moves to Ibrox without a transfer fee when his contract ends in the summer.
And his agent was sure that Broadfoot would give his all for St Mirren in their battle to avoid relegation from the Scottish Premier League.
"Anyone who saw Saturday's game, when he was captain and man of the match, will realise that it will not affect him and that he is committed to St Mirren totally," added Rankin.
