Land reform plans are "ambitious and radical", the environment minister has insisted amid calls for the proposals to go further.

It is estimated that half of the privately-owned land in Scotland is controlled by 432 people.

Dr Aileen McLeod said the Scottish Government's Land Reform Bill would be "potentially life-changing" for communities across Scotland.

The Bill will establish a permanent Scottish Land Commission, end business rate exemptions for shooting and deerstalking estates, give communities a right to buy land to further sustainable development and make information on who owns land and its value more readily available.

SNP ministers have come under pressure to strengthen the legislation after the party's conference in Aberdeen last month, where members rejected the plans on the basis they were not radical enough.

Delegates voted against a motion welcoming the introduction of the Bill by 570 votes to 440, with many calling for a wider debate.

Dr McLeod said she would remain open to suggestions for improvement as the Scottish Parliament's Rural Affairs Committee continues its scrutiny of the legislation.

She said: "There is no doubt that the Land Reform Bill will be potentially life-changing for individuals and communities across Scotland.

"Our proposals are about equality and fairness, empowering communities with practical powers and supporting sustainability.

"This ambitious and radical Bill is a vital next step in the land reform journey.

"The measures in the Bill make important changes to specific rights and responsibilities over land, including provisions to increase the transparency of land ownership, which have never before been seen in this country.

"I am open to ideas and suggestions relating to Scotland's land reform journey and will continue to work with all those with an interest to ensure that our land benefits the people of Scotland for generations to come."
