Label position and text alignment

Hi,

I try to right align text under Label but can't find how do this. I try to make 3 label like this :

Label 1 | Label 2 | Label 3

Here is my layout

<?xml version="1.0" encoding="UTF-8"?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="BasicForm.MainPage">
    <ContentPage.Content >

            <StackLayout Spacing = "0" Padding="10, 40, 10, 40" BackgroundColor="Green" Orientation="Horizontal" HorizontalOptions="FillAndExpand" VerticalOptions="Start">
                <Label x:Name="start" Font="Large" Text="t" HorizontalOptions="FillAndExpand" VerticalOptions="Center"></Label>
                <Label x:Name="middle" Font="Large" TextColor="Red" Text="e" HorizontalOptions="Center" VerticalOptions="Center"></Label>
                <Label x:Name="end" Font="Large" Text="st" HorizontalOptions="FillAndExpand" VerticalOptions="Center"></Label>
            </StackLayout>

    </ContentPage.Content>
</ContentPage>

Label 2 contain only one letter so it have to be on center of the screen. Label 1 is the start of the word (align right) and Label 3 the end of the word.
