Instead, he will talk of the need for “honesty and reflection”.He will also argue that it is time to give Britons “more breathing space” with a focus on policies that improve their everyday lives.Burnham’s inaugural speech as UK prime minister comes three days after his first address as Labour leader on Friday, when he was officially confirmed in that role. On Friday, he focused on calling for an end to division and “factionalism” in his party. Monday’s Downing Street speech, however, will focus more on the British nation.Andy Burnham gives a speech on Gravesend Town Pier, as he makes his first official visit as Labour leader last week.

Burnham is expected to argue that this “unprecedented turnover” in national leadership underlines the need for more “stable and responsible politics” in Britain.Follow irishtimes.com for updates throughout the day.
