       Mr Trump is the Republican frontrunner to enter the US presidential race later this year.

       Sir Richard, who led MI6 from 1999 to 2004, told Sky News: “From an intelligence perspective, the two things we need to worry about are Ukraine and China’s long-term behaviour globally.

       “You have to add a political threat I’m worried about — Trump’s re-election, which for the UK’s national security is problematic.

       “If Trump acts hastily and damages the Atlantic alliance, that’s a big deal for the UK.”
