In terms of more recent history, Roberts whole-heartedly embraced Thatcherism. He has remained a staunch backer of Prime Minister Margaret Thatcher and her socio-political legacy. In Roberts' opinion, Thatcher's insight to push the UK into a path in which it kept out of the Euro while still having strong ties to European economies has been validated by the Eurozone crisis in the aftermath of the world economic recession. After Tony Blair resigned as Prime Minister, Roberts assessed him as an "exemplary war leader" with his "vigorous prosecution of the War against Terror", which would leave him regarded as a "highly successful prime minister". In the 2016 UK Referendum on the EU, Roberts backed a Leave vote.
