Mark Iliffe: Interim Chair


As the interim chair of the North American Branch, I am aiming to build out our Branch to supporting the broader efforts of Lib Dems Overseas in bringing together people with our shared values. 

A professional geographer, I am currently living in New York, with previous postings to Washington DC, Tanzania and Uganda working primarily on developing policy and strengthening technical capacity in developing countries. After six years of field work, I am currently sitting behind a desk at an international organisation.
I joined the Lib Dems in 2019 and following our nascent efforts to organise our ‘local’ branch, took on the role of interim chair to help promote and foster our internationalist and liberal principles.


Nasreen Davidson: Interim Vice-Chair


I grew up in Brighton before heading to the City of London Polytechnic to study Business.  After joining the Student Democrats, my first step into activism was to march against the Tory government of this time, when they replaced student education grants with loans. 

New York City has been my home since 2001, where I live with my husband and two children.  I have worked in Human Resources all my career.

I consider myself a Liberal Democrat as the party has compassionate and practical social policies, is strong on the environment and international affairs.   I was very excited to join the new North America branch this year.  I am truly inspired by the opportunity to engage with fellow Liberals abroad and in the UK. 

I am determined to ensure there is a successful Liberal Democrat party that represents British values for integrity, fairness and equality at home and abroad.


James Croft: Secretary


I'm James Croft, a Londoner born and bred, who moved to the USA to study at Harvard before becoming clergy for a Humanist congregation in St. Louis, MO. During my time in the USA I have become deeply involved in activism, helping train politicians and leaders at the Harvard Kennedy School in how to mobilize and persuade people. I hope to use these skills to support the Liberal Democrat fightback.

I joined and was an activist for the Liberal Democrats as a teenager, and long to see the party return to the radical left-liberal politics which characterized our opposition to the Blair government. After a period of disillusionment during the coalition, I rejoined the party during the aftermath of Brexit, and am excited to work with the NA chapter to translate insights from US political campaigns for use by the Lib Dems

He was elected by his peers to serve on the Political Economy Advisory Board from 2006-2007.


Victoria Bateman: Membership Development Officer


As Membership Development Officer my role is to help grow the global Liberal Democrat membership base and retain existing members. It is an important time to encourage active political engagement in UK politics regardless of where Liberal Democrats are in the world. 

The EU referendum made me take stock of my involvement in politics, reigniting my passion to be more actively involved with the Liberal Democrats, support fair votes for all and act to stop the climate crisis. 

I grew up in Dorset and spent my young adult life living in London before moving to Canada in 2017 settling in Toronto, Ontario. I now work in the Advertising Technology industry as a Data Manager. I have been interested in politics since my teens studying Political Science and Philosophy university. Since university I have been long-term supporter of Liberal Democrat policies.
