Jens Stoltenberg and Boris Johnson are holding a press conference following their meeting in Brussels.
Stoltenberg and Johnson are expected to discuss the proposal of the UK to strengthen the defence capability of the alliance as well as the security situation around the Ukraine-Russia border crisis.
