Boris Johnson has appeared on a combative edition of the BBC's Andrew Marr Show - following a pledge by the broadcaster to refuse the prime minister a platform unless he agreed to an on-air grilling with Andrew Neil.
His on-air appearance comes after a BMG Research poll reveal the Conservative party's lead has been more than halved since the election was called.
Meanwhile Jeremy Corbyn has accused Boris Johnson of being “the world’s leading sycophant” towards Donald Trump as the Labour leader outlines his approach to foreign policy if elected.
The first of the Sunday shows will see Labour leader Jeremy Corbyn, the Liberal Democrats economic spokesman Sir Ed Davey and Foreign Secretary Dominic Raab appear on Sophy Ridge's Sky show.
Asked if anyone convicted of terror offences should service their full sentence – as Boris Johnson has now pledged – the Labour leader said: “Not necessarily, no.”

Jeremy Corbyn says terrorists can be released early if they have been 'rehabilitated'
Labour leader says prisons should also be 'a place where rehabilitation takes place'I wished our party had acted on it more rapidly at the very beginning and dealt with it at that point and also I want to make it very clear to the Jewish community, to the Muslim community and to any other community, anyone under threat because of persecution, because of attacks on their temples, mosques, synagogues or places of worship will be very secure under a Labour government.We will make sure there is full funding of all the protection measures they need and full respect for their religion, their faith and their place in our society.Jewish people suffered like no other in the 20th century through anti-Semitism in Germany which led to the horrors of the Holocaust and Jewish people have made an incredible contribution to my party, to our trade unions, to our life and intellectual life in this country.I value that and I thank them for everything that they do, I want all communities to be safe.
While the Lib Dems have made the seat a key target, Mr Raab has been dogged by national problems haunting him in his local area - with the parents of Harry Dunn arriving to campaign against him in the area.
The broadcaster said it was necessary to provide a slot for the prime minister in the wake of the terror attack on London Bridge that left two people dead and three injured after convicted and released terrorist Usman Khan stabbed members of the public.
In a statement, the corporation said: “As the national public service broadcaster, the BBC’s first priority must be its audience. In the wake of a major terrorist incident, we believe it is now in the public interest that the prime minister should be interviewed on our flagship Sunday political programme.

Boris Johnson denies huge Tory cuts were 'a mistake' and insists they played no part in London Bridge terror attack
Boris Johnson has denied huge Conservative funding cuts to probation services were “a mistake” and insisted they played no part in the London Bridge terror attack. A former top prosecutor says he personally warned the prime minister about the risk posed by freeing terrorists who had not been deradicalised, but was told there was “no money” for a programme. But, put underA bit of poll aggregation here – and as it stands it’s a fine margin between all out victory for Boris Johnson and all out failure.
Electoral Calculus puts the potential Conservative majority projected at this stage at somewhere between four – the same as the 2017 election dubbed a catastrophe for Theresa May – and 110.
