It was the cause of the biggest Conservative backbench rebellion in the last Parliament. But what about gay voters, what effect has it had on the way they intend to vote? Dave McMullan went to a meeting of gay people in a pub in south London.

Over the past four years Chris the cuckoo has visited twenty eight different countries, crossed the Sahara Desert eight times and reached speeds of up to 60mph. He’s just returned again to Suffolk after his annual migratory trip to Southern Africa. He was fitted with a satellite tag in May 2011 which means scientists now have four years’ worth of very detailed information which they describe as "unparalleled" and a "massive contribution to science".  Cuckoos are in huge decline, with almost three quarters wiped out since the late 80s. Chris Hewson is the lead scientist on the project at the British Trust for Ornithology.

Under a FOI request, two internal South Yorkshire Police documents have been made public for the first time. The reports, from 2003 and 2006, show the extent of the warnings the police were given in relation to child sexual exploitation in Rotherham and to a lesser extent Sheffield. They were written by an analyst for South Yorkshire police, and despite setting out links between drugs and violence and the exploiters, they did not lead to action. The documents have been referenced before in Alexis Jay's report. She led the Independent Inquiry into Child Sexual Exploitation in Rotherham and was the author of the investigation's report, published in August 2014. Dr Alan Billings is the South Yorkshire Police and Crime Commissioner.

Mount Everest remains open to climbers, despite avalanches triggered by last month's earthquake.  The Nepali government says it's up to climbers and organisers as permits have already been issued.  Most expedition groups have already called off their climbs. The Nepali group (the Sagarmatha Pollution Control Committee) which is responsible for deploying 'ice doctors' - experienced and expert Sherpas - say this spring season has now become "almost impossible" because the routes damaged "will take a long time" to reconstruct. The earthquake has killed more than 7,200 people, including at least 18 climbers on Everest who were hit by a massive avalanche that wiped out part of the base camp. Nick Talbot was attempting to be the first person with cystic fibrosis to climb Everest & was injured at base camp when an avalanche was triggered by the earthquake. He arrived back in the UK on Friday and Rebecca Stephens is the first British woman to reach the summit of Everest and chair of the charity, Himalayan Trust UK.

Casting our votes in the ballot box is one of the only things in life that's truly secret. The voter is presented with the ballot paper, a pencil and a sealed black box. Tonight, a play is being staged at the Donmar in London - and televised on More 4 - showing the last 90 minutes of voting day in a fictional polling station in a marginal seat (between 8.30 and 10.00 – i.e. in real time). The cast includes Catherine Tate and Judi Dench. James Graham is the playwright of The Vote.

Gregor Samsa, the character in Franz Kafka's Metamorphosis, is transformed into an insect in the 1915 novella. But what kind of insect exactly? Kafka never explicitly states it but there are plenty of clues - Gregor's "numerous legs", his concave back, the gum that he secretes and so on. David Baddiel has made a programme for Radio 4, broadcast this Saturday, with real insect experts, exploring what Gregor could be. David Baddiel and Beulah Garner is senior curator of Coleoptra with the Natural History Museum.
