'I'm a mother, not a superwoman,' Jacinda Ardern tells UK media

Prime Minister Jacinda Ardern has been interviewd by the BBC about her role as PM and mother, while visiting the UK amid Brexit deals this week.

Ms Ardern told BBC journalist Victoria Derbyshire there were definitely times she felt guilty for being so busy with work.

"The guilt of whether or not I'm a good enough daughter, sister, partner, mother… show me a woman who doesn't."

She explained that she is "a mother, not a superwoman" and that the perception that the latter is true "does a disservice to all women, it raises expectations that no one can meet".

Ms Ardern was also asked about Theresa May and her perspectives on the British Prime Minister's leadership.

She called Ms May a "woman of remarkable resilience".

"I have admiration for a number of politicians for what they have to navigate, and this is one of those situations," she said.

She said that coming from an MMP system and leading a government made up of three parties, she was used to constant negotiation and compromise with other parties.

The Prime Minister also penned an opinion piece for US magazine the Financial Times about kindness and mental wellbeing.

Ms Ardern begins the piece by referencing New Zealand's ability to "punch above our weight".

"Ours was the first country where all women won the right to vote back in 1893. In 1938, we were one of the first to introduce a cradle-to-grave social welfare system."

Ms Ardern says that New Zealand made a mistake when in the mid-eighties the government "slashed the top tax rate, dramatically cut public spending, removed regulations that were said to hamper business and vastly reduced welfare benefits paid to the sick, those caring for children and the unemployed".

She says countries need to move away from economies that see disproportionate benefits go to one group and leave others behind.

"From a purely economic perspective, there are clear benefits to supporting positive mental wellbeing, including enhanced productivity.

"As leaders we should not be afraid to reject the status quo, especially when an entire generation is doing just that."
