US politicians attend two-day Holyrood conference
A group of US politicians are at the Scottish Parliament for a two-day conference.
Members of the National Conference of State Legislatures (NCSL) are hearing from a variety of speakers, including Holyrood MSP Humza Yousaf.
Terie Norelli, president of the NCSL, said she was looking forward to the event which promised "insight, ideas and opinions".
She added she was looking forward to learning from Scots politicians.
More than 50 US State politicians, including speakers, Senate presidents and House leaders are due to attend.
Business leaders, including CBI Scotland chair Nosheena Mobarik, will also be at the event where discussions will take place on the global economic outlook, future worldwide energy supplies and legislative leadership.
Speaking before the conference, Ms Marwick said: "I am delighted that the Scottish Parliament will host this conference which is yet another opportunity to showcase both our country and parliament to an international audience.
"Holyrood is firmly established as an effective platform for debate both domestically and internationally. This conference will provide politicians on both sides of the Atlantic the opportunity to discuss issues of global significance such as the current economic climate.
"But it will also be an opportunity to share experiences, reflect on knowledge and to learn from each other's legislatures."
