Jeremy Corbyn tried to work around parliamentary rules so he would not have to declare his now-infamous "Wreathgate" visit to Tunisia.
His trip in late 2014 caused a scandal four years later when it resurfaced at the height of Labour's antisemitism crisis. It was revealed Mr Corbyn took part in a ceremony to lay a wreath for the Black September terrorists, who murdered Israeli athletes at the 1972 Munich Olympics.
New emails, unearthed by the Guido Fawkes blog, reveal Mr Corbyn asked staff to "keep it cheap" to ensure the trip came under the £660. Otherwise, he feared, it "has to be referred to debates etc".
"It sounds alright but will need to be very clear who is paying for it as I will have to declare anything over £600 [sic], unless thy [sic] can keep it cheap," he wrote to his office staff about the trip.
