Here is more from The Times at the London-based think tank Legatum Institute:
A think tank with close links to Conservative Brexiteers is be reviewed by the head of a parliamentary committee that scrutinises the work of the intelligence agencies.
Concerns have been raised about links between the Legatum Institute and the Brexit department and the background of the think tank’s main financier and founder, Christopher Chandler, a New Zealand-born tycoon who made part of his fortune with his company, Legatum Group, via investments in Russia.
Dominic Grieve, chairman of the intelligence and security committee, told The Sunday Times that he would “scope” the institute as part of preparations for investigation into Russian activities against the UK.
In the latest University of Pennsylvania think tank rankings, Legatum was named as the 82nd best think tank in Western Europe.
The Financial Times reports about a recent "purge" at the think tank (as does Daily Mail).
The think tank has rejected claims that it has links with Russian President Vladimir Putin.
Here is what openDemocracy has to say about who is behind Legatum's funding.
