ITV followed the BBC in scrapping its bid for hosting the debate after May and Corbyn failed to reach an agreement on the format of the discussions.
"ITV invited the Prime Minister and leader of the Opposition to appear in an ITV programme this Sunday evening, and we have been clear that it is up to those invited to decide whether they want to accept the invitation. ITV is developing its plans for covering the build-up and reaction to the crucial Commons vote next Tuesday, and a range of voices and opinions will be represented on the subject of Brexit in our output," ITV’s spokesperson said in a statement published on the broadcaster’s website.
May initially accepted the offer of the BBC to host the debate including political figures from various parties but Corbyn called the format a "mish-mash," opting for the ITV proposal to host the one-on-one debate which was subsequently withdrawn.
The Labour’s statement, quoted by ITV, suggested that May was scared of debating Corbyn.
On Tuesday, the UK lawmakers are set to vote the Brexit deal struck by May’s government and the European Union. The agreement has repeatedly been criticized by politicians from both May’s ruling Conservative Party and other political forces, including Corbyn.
