The embattled Labour leader has been accused of “burying his head in the sand” as he opted to visit the Middle East to meet refugees at Jordan migrant camps instead of attending the march, which attracted more than 100,000 people to the capital.
In further signs of frustration at the Labour’s incoherent Brexit stance, Remainer activists chanted “where’s Jeremy Corbyn?” as they marched from Pall Mall to Parliament in their thousands.
Angry Twitter users took to social media to berate Mr Corbyn’s over his priorities as the opposition leader.
One said: “Jeremy Corbyn is in Jordan today burying his head in the sand whilst the people march in the street against Brexit mass suicide.”
Anther said: “#WheresJeremyCorbyn? shows very clearly that patience has run out and the Labour leader has only himself to blame: the fight against Brexit is now also the fight against Corbyn.
One tweeted: “Where’s Jeremy Corbyn? Accidentally cooking up a Tory Brexit by failing to effectively OPPOSE, probably…”
A twitter user posted: “The biggest march yet against Brexit & Corbyn is hiding.”
Another added: “You had one shot. One opportunity. To capture everything you ever wanted. One moment. And @jeremycorbyn @UKLabour you blew it. 100,000+ people here today. Some reports say half a million. You ended up on the wrong side of history. Where’s Jeremy Corbyn? Where’s the Opposition?”
In Jordan, Mr Corbyn reportedly refused to answer questions about the anti-Brexit march.
Meanwhile, his senior advisor is said to have not known any details about the march or where it was even taking place, according to Sky News.
Instead Mr Corbyn called for Britain to play a full part in a EU deal on immigration – even after Brexit.
Speaking in Amman, Jordan, he said: “Whatever the outcome of Brexit we are human beings on the same planet.
“We are going to have to work with EU countries on the issue of migration.
“Germany has taken in a very large number of large number of Syrian refugees and other countries have closed their doors to them.
“Britain has taken in a very small number, but not even taken in the number we pledged to of children.
“I think it’s a very bad message.”
