David Cameron sent an email to members of his Conservative Party urging unity.
In an article for ITV News, Conservative councillor Mary Douglas talks gay marriage and urges David Cameron to return to 'core values'.
David Cameron has defended the equal marriage bill while Nick Clegg claims a civil partnership amendment is laced with an "ulterior motive".
The Mayor of London has tweeted a picture of him and the Prime Minister meeting community leaders in Woolwich.

"Clear and overwhelming message from the community meeting - London won't be divided by this sickening atrocity."

The point that the two suspects in this horrific attack were known to the security services has been widely reported.
You would not expect me to comment on this while a criminal investigation is ongoing. But what I will say is this.
As is the normal practice in these cases the Independent Police Complaints Commission will be able to review the actions of the police and the intelligence and security committee able to do the same for the wider agencies.
Nothing should be done to get in the way of their absolutely vital work.
The Prime Minister will speak to cameras at around 11am after he chaired the second COBRA meeting this morning.
Prime Minister David Cameron has said there are strong indications that the murder of a soldier in Woolwich was terror related.
Speaking in Paris, he said: "I have been briefed by the Home Secretary about this absolutely sickening attack in Woolwich in London.
"It is the most appalling crime. We are obviously urgently seeking and the police are urgently seeking the facts of the case but there are strong indications that it is a terrorist incident."
He added: "Tonight our thoughts should be with the victim and their families and friends. People across Britain. People in every community, I believe, will utterly condemn this attack. We have had these sorts of attacks before in our country and we never buckle in the face of them."
Prime Minister David Cameron said an EU deal to move towards full cross-border disclosure of tax information will give momentum to a G8 summit he will host next month in Northern Ireland on the same subject.
Talks in Brussels today claim to have removed obstruction by Luxembourg and Austria.
Both countries had previously prided themselves on their banking secrecy.
He said: "Tax evasion and aggressive tax avoidance are at the heart of the G8 summit, and there is real momentum behind this issue."
"We have a real opportunity to make this summer a turning point in breaking down the walls of corporate secrecy and get information on who really owns and controls companies."
EU leaders meeting in Brussels have discussed plans to fight tax fraud and close loopholes used by large corporations to minimise tax payments.
Prime Minister David Cameron said the EU has to be sure "that companies pay taxes and that means international collaboration, sharing of tax information."
Irish Prime Minister Enda Kenny has denied Ireland is cutting special tax deals with multi-national companies, including Apple.
He said: "Ireland has been one of the frontrunners, and will be, in regard to building a new international consensus."
Taoiseach Enda Kenny has rejected criticism of the Irish tax system after a US Senate committee claimed Apple used the country in a bid to avoid paying billions of dollars in earnings.
On arrival at the European Union summit, he said: "I'd like to repeat that Ireland's corporation tax rate is statute-based, is very clear, very transparent - we do not do special deals with individual companies in relation to that rate."
The Taoiseach said Ireland was one of the first countries to agree a scheme on sharing of tax information with the US.
"Multinationals, in their aggressive tax planning, operate in many jurisdictions. For that reason, Ireland has been very much to the forefront in having and building more international consensus as far as transparency in tax regimes is concerned," he added.
David Cameron said he believes in low taxes for businesses because he wants "Britain to be a winner in the global race" but said it was important to make sure companies pay what they should.
The Prime Minister spoke as he arrived at an European Union summit in Brussels.
Nick Clegg said he "cannot envisage any circumstances" that would see the coalition collapse before the 2015 general election.
The Deputy Prime Minister added that he "really thought" the Liberal Democrats and Conservatives would continue governing until that time.
David Cameron said it was "absolutely" his intention to keep the coalition together until the 2015 general election.
The Prime Minister told BBC Radio 4's Today programme there are some big and bold reforms ahead and dismissed suggestions the government was running out of steam.
On working with Nick Clegg until the next general election, he said: "That is absolutely my intention and has always been. This is a Government that has an enormous programme of work."
"To anyone who doubts the life there is left in the coalition, I would argue there is more to come. Very bold reforming and strong government, and that is what we will be right up till polling day," he added.
